FloPinguin d321c08d92 Nations now gang up on players and prioritize traitors/AFK players 🤖 (+ other improvements) (#2730)
## Description:

- **Nations now specifically target AFK players, traitors, and players
who are already being attacked (they gang up on them).** Depends on the
difficulty.
- Added ally assistance directly to the attack order (instead of calling
it separately beforehand).
- Added ally assistance to `findBestNukeTarget`.
- Removed some checks from `findBestNukeTarget` (not necessary; better
checks will follow in a dedicated nuking PR).
- Relation updates on attack now depend on difficulty (makes Easy &
Medium nations a bit easier).
- On betrayal, every nation in the game previously received a –40
relation penalty toward the betrayer. That was too extreme, so now this
only applies only to neighbors.
- Nations send fewer alliance requests now; it felt like too many
before.
- In team games, nations may now reject alliance requests more often
(depending on difficulty).
- To ensure there are enough non-friendly players to stop the crown with
nukes, nations may now reject alliance requests if the other player has
too many alliances (on Hard and Impossible difficulty).
- Rebalanced nation emoji usage a bit.
- Nations may now send an emoji when they get MIRVed.

FloPinguin f6412a5979 Re-Enable HumansVsNations 🎉 (#2689)
## Description:

**HumansVsNations is back!**

The original PR had an issue: only the nations listed in the map’s
`manifest.json` were being spawned, which resulted in completely
unbalanced games.

What did I change with this PR?

- The number of humans and nations is now always the same.
- If a map contains too many nations, we take a random subset.
- If a map doesn’t contain enough nations, we dynamically add additional
ones. These get random spawn locations, and their names are taken from
the new name generator `NationNames.ts`. The name generator was taken
from the closed PR #2245 (idea from @VariableVince).

These changes apply to private lobbies and singleplayer as well. In
singleplayer, you now simply play a 1-vs-1 against a nation.

For public lobbies, we use 50% of the regular team-game player count.
The remaining 50% are nations.

We are also using the Hard difficulty for HumansVsNations.
At the moment, it’s important that nations cheat a little because humans
can donate troops, whereas nations cannot, at least not yet. In the
future, we may make that work.

We might need to adjust the difficulty or do fine-tuning depending on
the humans’ win rate in production. Ideally, we want a ~50% win rate;
otherwise, the mode may become boring. Over time, humans will likely
develop strategies that nations can’t counter, in which case we’ll need
to improve the nation AI.

Here is a screenshot showing that the number of nations now matches the
number of humans in the private lobby UI:

src="https://github.com/user-attachments/assets/cb4ac6f6-13cc-452c-8cc5-7a500670d7f2"
/>

The `PuplicLobby` display was a bit bugged for HumansVsNations:

<img width="532" height="191" alt="Screenshot 2025-12-23 221832"
src="https://github.com/user-attachments/assets/3950bcd9-0072-4c28-b1a0-83c0a24e9b8e"
/>

So I fixed it to look like this;

## Description:

Previously, nations just spammed these two rather toxic emojis: 🤡😡

They now send fewer emojis while attacking, and the clown emoji is
reserved for special cases.

They got the ability to send emojis in much more cases:
- Human didn't donate enough for relation update
- Human did donate an ok amount
- Human did donate a lot
- Responding to emojis that they get sent from a human
- Nuke sent
- MIRV sent
- Retaliation warship sent
- Traitor tries to ally
- Threat asks for / accepts an alliance request
- Disliked human tries to ally
- Friendly human tries to ally
- They are getting attacked by very much troops
- They are getting attacked by very little troops
- Congratulating the winner
- Bragging with their crown
- Charming their allies
- Clown-Emoting traitors

YoussfeCantCode 1c52d20e83 Added pause functionality for private multiplayer games (#2657)
If this PR fixes an issue, link it below. If not, delete these two
lines.
Resolves #2491

## Description:
Adds pause/unpause functionality for private multiplayer games. Only the
lobby creator can pause the game, and all players see a pause overlay
when the game is paused.

  **Key features:**
- Lobby creator sees pause/play button in control panel (alongside
existing singleplayer/replay controls)
  - Server validates that only lobby creator can toggle pause
  - All players see "Game paused by Lobby Creator" overlay when paused
  - Game state freezes (no turn execution) while paused
  - Unpause resumes normal gameplay

  **Implementation details:**
- Server-side pause state (`isPaused`) prevents turn execution during
pause
- Each client receives `isLobbyCreator` flag in `GameStartInfo` to
show/hide pause button
- Added `TogglePauseIntent` that broadcasts to all clients via
`NoOpExecution`
  - New `PauseOverlay` component (shows in single player also)

FloPinguin 6d2ac30526 Fix bots no longer attacking humans 🤖 (#2690)
## Description:

A small number of people are complaining that bots no longer attack them
and that "This has broken the factory farming strat".
In the old #2550 I somehow added that bots on easy difficulty don't
attack humans and nations anymore.
And public games are on easy difficulty now.
But I think the difficulty should actually only change nation behavior,
not bot behavior. Their attacks are harmless anyways.
So lets remove that little check.
Also let `shouldAttack()` return true for bots.

FloPinguin 86d1ac6c62 Nations now counter warship infestations 🚢 (#2658)
## Description:

Relevant for singleplayer and HumansVsNations: 
Humans sometimes try to flood the entire ocean with warships. The goal
is to dominate the trade and to block transport ships.

The already existing `trackTransportShipsAndRetaliate` and
`trackTradeShipsAndRetaliate` methods can't stop these large scale
infestations, the nations are completely helpless.

The new `counterWarshipInfestation` method checks if a nation is one of
the top 3 richest players (Enough money for warships) and if any enemy
(or enemy team) has accumulated more than 10 (for teams total 15)
warships, then builds a counter-warship targeting that threat.

This feature only activates on Hard or Impossible difficulty.

Thats how it can look, nations send out a warship every couple of
seconds, until the infestation threat is gone:

FloPinguin 6afaf932a5 Make easy and medium nations less aggressive 📊 (#2671)
## Description:

1. Players complained that they have problems allying with nations in
the earlygame. So I added an `isEarlygame()` check to
`AllianceBehavior`. This should make the easier difficulties much easier
:)

2. The attack order of nations now depends on the difficulty. Easy and
medium nations got dumbed down, they now take nuked territory before
retaliating against attacks again.

3. The attack rate now depends on the difficulty. Easy nations are
reacting slower than impossible nations (to make sure the number of sent
alliance requests stays the same I removed the difficulty check in
`maybeSendAllianceRequests()`).

4. On easy and medium difficulty nations will sometimes just skip an
attack if the enemy is a human (`shouldAttack()`). But this did not
apply for the nuking logic. Now it does, which makes the easier
difficulties a bit easier.

5. I tuned the `getBotAttackMaxParallelism()` method a bit. The nations
are doing a bit less parallel bot attacks now, which makes the easier
difficulties a bit easier.

6. The settings in MIRVBehavior now depend on the difficulty. On easy
difficulty, nations will only send MIRVs very rarely.

7. Unrelated MIRVBehavior Cleanup: There was a 2 second cooldown and
cache logic. But it was completely useless because `considerMIRV()` is
only called every 4-8 seconds by NationExecution. So I removed it.

8. Unrelated little cleanup: I made a couple of methods `private`

FloPinguin 183b0ae4cf Fix: Optimize nation random boat targeting by skipping unreachable players 🚢 (#2660)
## Description:

Saw lots of `"cannot send ship to Player"` warnings in the console.
It was caused by `randomBoatTarget` not checking if the target is
reachable by boat.
It also caused the for loop in `randomBoatTarget` to exit too early (=>
no boat sent).
So I added a `canBuildTransportShip` check. Because this runs expensive
(?) pathfinding I added a `unreachablePlayers` Set to optimize
performance.

FloPinguin af1e05961c Cleanup nations (Part 2) 🧹 (#2647)
## Description:

1. Moved the currently very small betrayal logic from `AiAttackBehavior`
to `NationAllianceBehavior` because it makes more sense to have it
there.

3. Very small bugfix in `AiAttackBehavior::shouldAttack()`: the numbers
in the two `random.chance` calls were the wrong way round.

4. `NationExecution` was quite big and a lot of it was about MIRVs. So I
moved all the MIRV logic to the new `NationMIRVBehavior`.

5. `emoji()` and `maybeSendEmoji()` did not really fit in
`AiAttackBehavior`. So I moved it to the new `NationEmojiBehavior` (and
did some renaming for clarity). I'm planning to extend that class in a
future PR.

2. Reordered methods in `AiAttackBehavior` to easily find related
methods.
6. Reordered methods in `NationExecution` to easily find related
methods.

FloPinguin 4d5bb7a835 Cleanup nations (Part 1) 🧹 (#2637)
## Description:

1. Using the wording `"Nation"`, `"FakeHuman"` and `"NPC"` at the same
time is confusing.
So I renamed every mention of `"FakeHuman"` and `"NPC"` in the entire
project to `"Nation"`. Just like they are called ingame.

2. `BotBehavior.ts` was originally intended for sharing the logic
between nations and bots.
But at the moment, the logic there isn't really shared and it's
basically just about attacking.
So I renamed `BotBehavior.ts` to `AiAttackBehavior.ts`. I use "Ai" to
indicate that this file is used by bots AND nations.

3. Moved `execuction/utils/AllianceBehavior.ts` to
`execuction/nation/NationAllianceBehavior.ts` to make sure everybody
understands that this file is not about alliances in general. It's just
about nations and how they handle alliances.

4. Removed `difficultyModifier` from `DefaultConfig`. It's unused and I
think we usually want to finetune the difficulty instead of using that
method.

5. Added `assertNever` in all `switch (difficulty)` default cases.

FloPinguin 058bb44273 Fix nation relation exploit 🔧 (#2523)
## Description:

Saw this in an Enzo video about beating impossible nations:

You can just donate 1% gold / 1% troops to a nation to get a friendly
relation with them.

This PR adds randomized minimum donation requirements based on the
difficulty.
Randomized in a way that there is a minimum someone has to donate to
surely get the relation improvement, but you can also gamble and send
less.

For troop donations, the minimum is calculated based on what percentage
of their troops the sender donated.

For gold donations, it's fixed values. We cannot use percentages here
because “having nearly no gold” is a usual case. Donating 100% of your
gold wouldn’t hurt if you just spent all your gold on buildings.

I tried to add tests for this but it's really horrible. Because the test
would have to wait until the relation update from the alliance accepting
is gone (we need to have an alliance to send stuff), has returned to
Neutral, and then changes back to Friendly after the donation.

FloPinguin dfe33a05e9 Improved the nation alliance request logic 🤝 Massive upgrade to singleplayer fun (#2606)
## Response to alliance requests

Previously the way nations responded to alliance requests was quite
simple / boring / exploitable. Basically you couldn't ally them if you
had a bad relation with them, or if you had too many alliances.
Otherwise they would just take it.

Now there is a **complete decision tree which is based on the
difficulty**. The nations should also feel more human now.

For example, just like humans, nations will now consider to take an
alliance even if you have a bad relation with them (If you are a
threat).

Also, nations no longer check if YOU have too many alliances. Now they
do what humans do: Check if THEY have too many alliances (they want to
be able to attack somebody).

Another big change is the default case: Previously it was just `return
true`. Now it's `return isAlliancePartnerSimilarlyStrong`. So they do
what humans do: Take a quick look at their troop count before allying
them.

## Sending alliance requests

Previously alliance requests were sent randomly. Quite boring.

Now we use the same decision tree as for responding.

## Alliance extension requests

They also use the same decision tree.

## Tests

Tested it a lot in singleplayer.
I have planned to add unit tests for all the nation/bot stuff in the
upcoming cleanup phase.

FloPinguin 427e462fe5 Revamp nation/bot enemy selection 🗡️ (#2550)
## Description:

I closed my previous PR #2533 which was already reviewed by evan (but
not yet merged) because I noticed some issues.
Which led me to changing the enemy selection entirely. 

Nations / Bots previously had a fixed enemy which they kept for 100
ticks (10 seconds). This could make them react too late and feel slow.
Now they are a bit more responsive.

But the main benefit: Without a fixed enemy we can do multiple
sendAttack() on the same tick, which allowed me to give impossible
nations extremely efficient parallel bot attacks:


https://github.com/user-attachments/assets/38f65623-fbf0-4e98-a833-5fcba2ee6eee

Previously nations were so slow in taking out bots that you could even
encircle them on the Archiran map...
Now they are like 200% faster (but only on the impossible difficulty)

## Nuke enemy selection

Previously, the enemy for troop attacks and nukes was identical. Now, as
we no longer have a fixed enemy in BotBehaviour, I added
findBestNukeTarget() to select better nuke-targets. I will probably open
a PR soon which makes nations nuke the crown :)

## Betrayal logic

While revamping the attack logic I had to work on the betrayal logic,
which was quite confusing, with many negations. And the betrayals were
just random.
So I made it easier to understand with maybeBetrayAndAttack().
Now it does betray friends if we have 10 times more troops than them. I
will improve that method in a future PR, but already now it should be
better than just betraying randomly.

## Attack order

Previously, nations attacked in this order:

- TerraNullius (Untaken land and nuked territory)
- Bots
- Retaliate against incoming attacks

Now its in this order:

- TerraNullius (Untaken land)
- Retaliate against incoming attacks
- Bots
- TerraNullius (Nuked territory)

So the changes are these:

- After throwing a nuke onto a nation, they will no longer ignore
incoming attacks. Previously they attacked the nuked territory first.
Very common singleplayer problem.
- Nations now retaliate against incoming attacks before attacking bots.
Previously you could attack a nation but they did not care because there
were still bots left.

I also changed the attack order of bots a bit (retaliate before
attacking randoms), but that isn't even noticeable.

## Big bug fixed

Additionally, I fixed a big bug: selectEnemy() oftentimes returned null
(because of enemySanityCheck) and therefore no attack happened.
This was especially visible in games where nations are surrounded by
friends (Team games and nations vs humans).
This was also the reason why Enzo could play nations vs humans in
singleplayer and NO NATION of the much bigger nation team would try to
attack him.

VariableVince 8f32746bb2 Special bot names (#2552)
## Description:

Special bot names. If the solution seems convoluted for such an easy
thing, that is because: not all bots find a spawn position, so only
assign a candidate name after finding a spawn. And the first few are
almost always overwritten by Nation spawns so the first 20 just get a
random name. Only then do we assign from the provided lists. For the
random names, some might get the same name but that's not an issue as
no-one will notice and they're off the map quite fast anyway.

## Description:

- Removed the temporary UnitType.Construction and embedded construction
state into real units via isUnderConstruction().
- Centralized non-structure spawning to perform a single validation
right before unit creation/launch.
- Updated UI layers to render construction state without relying on the
removed enum.
- Adjusted and created tests to match the new flow and to cover the
no-refundscenarios.

# Tests updated 
- tests/economy/ConstructionGold.test.ts: covers structure cost
deduction and income, tolerant of passive income; ensures no refunds
during construction.
- tests/nukes/HydrogenAndMirv.test.ts: accounts for single-check launch
flow; MIRV test targets a player-owned tile; ensures launch after
payment.
- tests/client/graphics/UILayer.test.ts: mocks now provide
isUnderConstruction and real type strings;

Loacky 024285389a Implement donation troops/gold between human players after forming an alliance (#2450)
Resolves #2448 

Hi team,

I've implemented and locally tested the alliance-related changes
(including unit tests and some manual simulation with multiple browser
profiles).
Unfortunately I wasn't able to perform full end-to-end testing on the
live game server with two separate machines/accounts.

If someone on the team (or another contributor) can verify the alliance
flow with two real players, that would be greatly appreciated before
merging. Happy to hop on a call or provide any clarification needed.

Thanks!

## Description:

Fixed a race condition bug where donations (troops/gold) between human
players failed after forming an alliance. The issue was caused by a
one-tick delay in `AllianceRequestReplyExecution`: the alliance
acceptance logic ran in `tick()` instead of `init()`, meaning the
alliance wasn't created until the tick after the execution was added. If
a donation execution was added in the same turn as the alliance
acceptance, it would fail the `isFriendly()` check because the alliance
didn't exist yet.

**Root cause:** When human players formed alliances via reply, the
execution model delayed alliance creation by one tick, while bots called
`accept()` directly without this delay.

**Solution:** Moved alliance acceptance logic from `tick()` to `init()`
in `AllianceRequestReplyExecution.ts`, ensuring immediate alliance
creation and eliminating race conditions with donations.

**Changes:**
- Modified
`src/core/execution/alliance/AllianceRequestReplyExecution.ts` to
process alliance replies in `init()` instead of `tick()`
- Added comprehensive test suite `tests/AllianceDonation.test.ts` with 5
test cases covering donation scenarios after alliance formation (reply
and mutual request flows)
- All existing tests pass (323 total)

## Please complete the following:

- [x] I have added screenshots for all UI updates (N/A - backend logic
fix only)
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file (N/A - no user-facing text
changes)

responsibility for any bugs introduced

unique-coder-124 599342995c fix(2388): troop penalty applied to boat retreat (#2389)
Description:
There is a boating exploit where players could repeatedly send and
retreat boats to effectively increase troop regeneration and maintain
almost double the max troop cap. This PR fixes #2388.

Summary
This pr adds a troop penalty to the boat retreats in
src/core/execution/TransportShipExecution.ts of 25 percent (currently
the same as land attacks, but may require fine tuning). this prevents,
to some degree, the ability to stockpile large amounts of troops above
your max cap.

Testing
I tested the change locally and confirmed that the troop penalty is
applied at the correct times and under the correct conditions, i.e. it
is only applied on successful retreat (applying on reteat initiation may
be confusing if you are told you have lost troops if the transport ship
never arrives anyway). The boating exploit is far less effective with
this fix in place.

Notes
- This is a exploit and does not introduce any new features.
- Existing game behavior outside the retreat penalty remains unchanged.
- The attack message is the same as the land attack, so the translation
should already be present.

Checklist
- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory

VariableVince 9c24d29824 AFK team mate v2: better ship handling + tests + bugfix (#2396)
## Description:

See PR https://github.com/openfrontio/OpenFrontIO/pull/2203

It was reverted. This unreverts it, with an added fix for boat troops
not getting returned to owner. And small comment updates. And a const
for boatOwner to re-use.

The added bugfix is check for this.sourceTile === null in the retreat()
function in AttackExecution. A boat attack always sets removeTroops to
false because the troops were already removed from owner troops when the
boat departed. They don't have to be removed again in AttackExecution
init, when the boat lands and the attack starts. But at the end of the
attack, in retreat() in AttackExecution, the starting/boat troops still
need to be returned to the owner. That's why even if removeTroops is
false, when sourceTile is not null (only when it's a boat attack) we add
back the troops to the owner.

FloPinguin 0200df3ce1 Let nations send retaliation warships! (#2376)
## Description:

This PR is intended to increase singleplayer fun.
This is a follow-up to my previous PR #2161, which made the
"Hiding-Strategy on small islands" harder.

But its still possible. You can easily warship-infest the map and get
rich from the trade, even though you are playing on impossible
difficulty.
Also you can easily hinder the nations to, for example, get from the
left to the right side of the world map. So you are always in full
control of the game.

This PR makes nations send a warship if their troop transport boat got
destroyed. The warship will travel to the location where the boat got
destroyed.
Because the nations send more boats now (previous PR), this actual has
an impact and there is more action on the map now :)

The chance of retaliation is based on the game difficulty.

Philipp Allweyer 5dde4cc16d Extend SAM Range to cover Hydros when stacked (#2351)
## Description:

Implements SAM range extension for stacked SAMs to cover hydros as
requested in #2347 and many times from users in discord.
This implementation is as simple as possible: At level 5 and higher,
SAMs extend their range to the range of a hydrogen bomb + 10 for a small
safety margin. Levels 2-4 are interpolated between.

Screenshot to show the sizes compared to a hydro:
<img width="400" alt="image"
src="https://github.com/user-attachments/assets/a857d66c-e3d4-467f-855f-3539cc90b719"
/>

Everything works together with the new range UI, although I might need
to unify with / rebase on #2350. Not yet tested with #2348, but
shouldn't be an issue.

## Input needed:
- Should I add tests for this?
- This is in effect a massive buff to SAMs, might be too strong. Popular
ideas / suggestions from Discord to balance things:
  - Cap the SAM upgrade level at the maximum range (easy to do)
- Alternative, instead of capping the level, decrease the range when
missiles are reloading
- Increase the cost scaling for SAMs per stack, and scale way higher
(e.g. 1.5M > 3M > 4.5M > 6M or something like that) (UI integration
unclear, breaks with existing cost logic)
  - Decrease SAM hit probability for Hydros

I'm happy to implement any of these paths, or just roll with the simple
way it's set up now, just let me know.

## Description:

The **proximityBonusPortsNb** function increased the likelihood a
tradeship would go to a nearby port. But now that trade gold is nerfed
from nearby ports, we shouldn't encourage trading with ports that are
too close. So now add another factor **tradeShipShortRangeDebuff** That
cancels out the proximity bonus if the port is too close.

Now tradeships are encouraged to go to ports that are close, but not too
close.

Also move tradingPorts method to the PortExecution class because that's
the only place it's used.

FloPinguin f607f6d66b Nations rarely sent boats, now they do! (#2161)
## Description:

### Nations rarely sent random boats. Now they are sending twice as
many.
It feels right now, not too many and not too few random boats. 
To make sure that small island nations with, for example, 10k troops
don't repeatedly spam boats into an nation with 1.5M troops (that makes
no sense), they no longer send boats to opponents which have more than
twice the amount of troops.

### There was a bug in the random boat sending. 

It did not check if the target is the player himself.
That caused console warnings and a reduced amount of boat-sending.

### The Hiding-Strategy on small islands on the impossible difficulty is
now harder!

Because the random-boat-sending-method preferred large landmasses
instead of small islands (it randomly selects a valid tile),
human-players could easily hide on them, play a
warship-infestation-strat and nearly NEVER get boat-attacked by nations.

I implemented that the random boat functionality now searches for bots
and untaken tiles before searching for nations / humans. That way, they
will try to take some of these tiny islands before the human-player
does. Also its cool to see nations playing on the entire available
land-tiles instead of just the bigger landmasses.

Fixes #1916 (Please check this issue for screenshots and more info)

### Nations now boat-attack other nations more often!
If there are two nations on two very large landmasses, which are divided
by water, they nearly NEVER attacked each other.

Most attack-functionality relies on the enemies sharing a border. If
they don't have one, the only possible attack-mechanism is the
random-boat-sending. But for very large landmasses (=> very large number
of coastal tiles) it can take a long, long time before it randomly
selects an enemy-tile. With the bug I described above ("did not check if
the target is the player himself") it took even longer. And on the
world-map, the nations have to go over iceland, this is also very
unlikely.

So I implemented the method selectNearestIslandEnemy, which specifically
doesn't cares about borders. It makes sure that a nation always has
someone to attack. This method only gets used as a fallback, and only if
a nation has no borders with anybody.

Fixes #1916 (Please check this issue for screenshots and more info)

VariableVince 896a8ebe92 AFK team mate: better ship handling + tests + bugfix (#2203)
## Description:

Have AFK player's Warships not attack team members ships, like Transport
Ships boating in. If team mate conquers the AFK player, transfer over
Warships and Transport Ships to conqueror. The transfered Transport
ships attack in the name of the new owner when landing, and when they
are retreated they move back to a new owner shore tile if they have any.

Added tests. Expectation is this PR will be merged in v26 as the real
solution for the temporary workaround of deleting warships.

**Currently:**
- An AFK player can be attacked without troop loss by their team
members. For this purpose, isFriendly now returns false if the other
player isDisconnected
- But that meant Warships would get False from isFriendly too, and
attack the ships and boats of their team members.
- [Temporary workaround was to delete
warships](https://github.com/openfrontio/OpenFrontIO/commit/eea8db7a06aed50c005db35ad55ece026f7a3643)
as soon as the player was deemed AFK. But this is a disadvantage to the
team. For example the AFK player could have 6 warships in the waters,
either defending team land or helping the team cross over to the enemy
team.
- Transport Ships that were on the way to attack, were still deleted
after the AFK player was conquered. But this is also a disadvantage, if
say a transport ship has just managed to breach through to the enemy
lands despite warships all around. That could have made the win for the
team.

(Left to think about: do we want to transfer part of the defender troops
to the isOnSameTeam attacker? Defender looses less troops in the attack
from their team mate. You'd expect troops to lay down their arms mostly,
if the attacker is on the same team and doesn't loose troops themselves.
Those troops that they loose less than normal, are then added to the
attacker once they've been deemed conqueror. The enemy team can still
attack and do normal damage, and can still also be the conqueror so the
team members have to be fast.)

**Changes in this PR:**
- GameImpl > conquerPlayer: Transfer ownership of the warships to the
conquerer of their lands. If the conqueror is not a team member (other
team can still attack, in their case with troop loss), they won't get
the warships and the ships will be deleted like normal. If the conqueror
is a team member, have them capture the warships.
(Captures need to happen in conquerPlayer since this is right before the
last tiles are conquered and PlayerExecution finds out the player is
dead and deletes its units. Captures will be recorded in the stats just
like normal. Things like this add an extra incentive to be the fastest
to conquer the AFK player, next to getting their gold which is also
recorded in stats. The normal Event Box messages are also displayed.)

- GameImpl > conquerPlayer: Also transfer Transport Ships. As a note:
the limit of 3 transport ships concurrently out on water for one player,
can be exceeded in this specific case (the boatMaxNumber is only checked
for canBuild via TransportShipUtils, and in the init of a
TransportShipExecution, not for an existing TransportShipExecution with
a changing owner). This keeps the situation even for the team in terms
of ships that are already out to attack, which is fair.
captureUnit/setOwner won't do the full job here though, so changes in
TransportShipExecution are needed.
- TransportShipExecution: Added originalOwner. So we can check within
the execution itself if the Original owner disconnected, and if so if
the new owner is on the same team. Only in that case change private
this.attacker. This.attacker can still not be changed from the outside
in this way. Find new src of new owner to retreat boat to if needed, and
if new owner has no shore set it to null so the boat will be deleted
upon retreat. To find new src tile of new owner, use
bestTransportShipSpawn instead of canBuild because canBuild checks for
max boats = 3 etcera but the boat is already on its way so those checks
don't apply (we could get false back from canBuild because there's 3
ships out, while we only need to find the source tile so use
bestTransportShipSpawn).
- TransportShipUtils: to use bestTransportShipSpawn to find new owner
source tile to retreat to, we need to make sure it can handle a new
owner without shore tiles. When the new owner has no shore tiles
(candidates.length === 0), return false. This way it won't go on to call
MiniAStar which would have SerialAStar error on an empty this.sources
array.


- WarshipExecution: Changed isFriendly. This makes sure we have the
wanted behavior: allied/team ships should not attack each other once one
of their owners goes AFK.

- AttackExecution: added one more test specifically to check if attack
on AFK teammate is still witthout troop loss "Player can attack
disconnected team mate without troop loss". Also a bugfix that I left in
after removing a related change from this PR: Add a check for
removeTroops === false in the retreat() function, so at the end of the
attack we don't add troops back to owner troops if they were never
removed in the init. This check in retreat() is actually a bug fix
because removeTroops is in the constructor and can be set to True, but
in retreat() troops would then have been given back after not being
removed at init.

- DefaultConfig: small addition to comment.

- Disconnected.test.ts: added tests. Added useRealAttackLogic because at
least "Player can attack disconnected team mate without troop loss"
needs to use the real attackLogic.
- TestConfig: new class useRealAttackLogic extends TestConfig class, so
a test setup can use the real attackLogic from DefaultConfig instead of
the mock function in TestConfig.
- Setup.ts: for the test setup, add parameter to accept
useRealAttackLogic extension class. Defaults to TestConfig.

VariableVince 320a494ff4 Remove redundant function from FakeHumanExecution (#2335)
## Description:

Removed unused code.

PR https://github.com/openfrontio/OpenFrontIO/pull/2044 introduced

replaced by "betray" in BotBehavior, called in a chain of functions
resulting in the behavior that "maybeConsiderBetrayal" originally
intended:

Sam Bokai af86a9222f Feature: Enable FakeHumans ("Nation Bots") to Launch MIRVs Strategically (#2225)
## Description:

> [!IMPORTANT]
> Try here: https://mirv-test.openfront.dev/ 

> [!NOTE]
> Blocks PRs:
> - #2244 
> - #2263

### Summary
Implements intelligent MIRV usage for fakehuman players, enabling them
to make strategic nuclear strikes based on game state analysis.
 
### Changes

#### Core FakeHuman Strategy (`FakeHumanExecution.ts`)
- **MIRV Decision System**: Added `considerMIRV()` method that evaluates
game state and determines optimal MIRV usage
- **Three Strategic Targeting Modes**:
1. **Counter-MIRV**: Retaliatory strikes against players actively
launching MIRVs at the fakehuman
2. **Victory Denial**: Preemptive strikes against players approaching
win conditions
     - Team threshold: n% of total land (configurable)
     - Individual threshold: n% of total land (configurable)
3. **Steamroll Prevention**: Strikes against players with dominant city
counts (n% ahead of next competitor)

#### FakeHuman Behavior Tuning
- **Cooldown System**: n-minute cooldown between MIRV attempts
(configurable)
- **Failure Rate**: ~n% chance of cooldown trigger without launch
(simulates human hesitation/resource management; configurable)
- **Territory Targeting**: Centers MIRV strikes on enemy territory
center-of-mass for maximum impact

#### Technical Improvements
- **Type Safety**: Updated `UnitParamsMap` to include `targetTile`
parameter for MIRV units
- **Execution Flow**: Integrated MIRV consideration into fakehuman tick
cycle outside of standard attack logic, due to its holistic strategic
nature

### Game Balance Impact
- **FakeHuman Threat Level**: Increases late-game fakehuman
competitiveness
- **Endgame Dynamics**: Prevents runaway victories, extends game tension

### Breaking Changes
None - purely additive feature
