Resolves#4165
## Description:
This PR update the test checking validity of Nation Names to include the
new character constraint explained below.
It also fixes the 10 Nations that invalid characters (that did not
render correctly on the map).
**The new character constraint**
According to testing, the game map renders correctly all safe
Extended-ASCII characters (non colored in www.ascii-code.com =
[0x20–0x7E] or [0xA0-0xFF]). Other characters, when present in Nation
Names, are rendered correctly in the rest of the game but not on the
map, where they are trimmed to the last byte, which is then interpreted
as Extended-ASCII and rendered if possible.
**How to quickly check my assertion**
1. Change the file resources/maps/world/manifest.json, renaming one of
the countries to "a.á.आ!š!慢!".
2. Start a game on the world map without any bots
3. Verify that the nation name is well displayed in its overlay but is
shown as "a.á.!a!b!" on the map.
(characters before a point are preserved, but characters before an
exclamation mark are missing/changed).
4. run `npm run test` and notice that the NationName test fails and
lists the three non-valid characters.
Explanation: The string is represented in UNICODE-16 as
\u0061\u002e\u00e1\u002e\u0906\u0021\u0161\u0021\u6162\u0021.
Which, when we keep only the right-most byte of each character gives:
61 2e e1 2e 06 21 61 21 62 21
And, converted in Extended-ASCII gives:
a.á.�!a!b!
(which matches the showed name if we discard the control character).
**The 10 Nations which needed a fix**
Utqiaġvik from the Bearing Strait.
Ar Rayyān from the Strait of Hormuz.
6 Nations in the Bosphorus Straits.
2 Easter-egg Nations from Luna.
The 8 real-world Nations were adapted by simply removing the diacritics
(after confirmation from a speaker of arabic and turkish, but sadly none
for the Utqiaġvik Nation).
The Secret Base from Luna was renamed "T0Þ $e¢®ët Mi|¡tªr¥ ß@§£", all
within Extended-ASCII, keeping the same spirit as the original name.
However, the Monolith Nation (previously named ▊, without any flag) has
changed quite a lot and needs some explanation.
**Easter-egg Nation Monolith**
The new name is "ΜΟΝΟʟΙȚΗ", which is entirely outside of the valid
character zone but in a way that entirely disappears on the map (as the
आ character in the example above). This means that on the map, the
Nation has no name and only its Monolith-flag.
However, in all other places (leaderboard, overlay, alliances, warnings,
etc.) the name is displayed correctly.
The included test excludes this precise name from its violation list.

## Description:
- Adds a map of Hong Kong. The size is 2781x1997 with land area of 41%
(2.2mil pixels). The islands, straits, harbors, coastlines and
peninsulas make for some very intersting gameplay.
- HK is the second densest place on earth. To simulate this, there are
71 nations based on districts, parks, islands, etc. (Kowloon and HK
Island are so crowded with nations, there may be only 1-2 tribes that
spawn there!)
- Large coastal plains, passes and mountain ranges across islands and
the mainland

Fixes#4069
Adds map of the Caribbean sea and its islands. Archipelago map with lots
of islands, lots of water and a lot of trade.
This map has multiple large landmasses of similar size to prevent
steamrolls (the largest islands and landmasses are around 30%), and
many, many small islands where players can survive and trade. Players
will have to island hop in order to win. 34 nations of Caribbean
countries and territories, with an extra 28 AdditionalNations for a
total of 62 nations for crowded HvN.
Heavy Island maps are very popular in the broader community and we dont
have one for v32, so i figured it would be nice to have a very requested
and popular world location
570k land tiles, fairly small for a map, would be right placed before
World (600k tiles). Also adds some flags of caribbean regions.

## Description:
"A high-stakes naval theater where empires clash over narrow corridors,
bottleneck straits, and heavily fortified shorelines."
Modeled to the exact strategic proportions of the classic Black Sea map,
Yellow Sea shifts the focus of global conflict to East Asia. The map is
defined by its massive central body of water, making naval dominance
absolutely essential for survival. However, unlike wide-open oceans,
control of the Yellow Sea is entirely dictated by its unique coastal
geography.
The Shandong And Liaoning Peninsulas are The definitive feature of the
map. Two massive, opposing peninsulas project deep into the sea, acting
as natural, heavily contestable daggers. They create tight naval choke
points in the central waters while forcing land-based players into
brutal, linear frontlines where every pixel of territory is bought with
blood.
The Continental Rim: A sprawling mainland coast wraps around the
northern and western edges of the map, offering expansive land routes
for players who prefer sweeping land invasions over amphibious assaults.
Scale Class: Medium
Gameplay Style: Naval/Land Hybrid, Tactical Choke Points, Frontline

## Description:
Labyrinth is a maze type map. My attempt at making a more chess style
board for play. Games with bots appear stable at over 45min average run
times. The map has been setup for team spawn zones for 2, 3, 4, 5, 6,
and 7 teams. Some of the team spawns for odd numbers are experimental
and I would like to see how they play out with live players. Additional
nation names included. There are other design factors like each of the
large squares being within the blast radius of a hydro; small islands
are within the blast radius of nukes.
This is meant as a slower playing game. My intentions are to get some
sort of literal rotation of the map in the future if easily implemented.
That way every time players load the game there would be some
randomization.
As an additional note one of my last edit to the map was the "+" shape
to the islands to allow train passage. Zooming out I can see now that
the pattern is squares and + through out. Did not fully intend on that,
but it felt like good vibes.

## Description:
Five performance improvements to the map generator, measured on three
maps of increasing size. End-to-end time on `world` improved ~15×, heap
allocations ~19×.
| Map | Before | After | Speedup |
|-----|--------|-------|---------|
| bosphorusstraits (~612K tiles) | 578ms / 594MB | 45ms / 134MB | 13× /
4.4× |
| world (~2M tiles) | 2333ms / 2128MB | 150ms / 553MB | 15× / 3.8× |
| giantworldmap (~8M tiles) | 10701ms / 9300MB | 635ms / 2509MB | 17× /
3.7× |
Changes (one commit each):
- **`--workers` flag**: bounds concurrent map processing to limit peak
memory
- **Flat `[]bool` visited sets**: replaced `map[string]bool` keyed by
`fmt.Sprintf` with flat `[]bool` indexed `x*height+y` — the dominant
cost
- **`neighborCoords` with stack buffer**: eliminates per-call slice
allocation for neighbour lookups
- **`Terrain` struct 24→16 bytes**: field reorder + `uint8` type for
`TerrainType`
- **Nil buffers early**: releases image/terrain arrays as soon as
they're no longer needed
- **BFS mark-visited on push**: each tile enters the queue once instead
of up to 4×, halving queue memory
also fixes a bug (according to Claude):
Here's the bug: createMiniMap downscales by averaging/sampling 2x2
blocks, copying field values across — including Ocean=true from the
parent scale. When a single connected ocean at 1x splits into multiple
disconnected bodies at 4x (because narrow water channels disappear when
you halve resolution), those smaller fragments still carry Ocean=true
from the carryover. The 4x processWater call picks the new largest
fragment and sets it to Ocean=true, but never clears the others — so
multiple disconnected bodies end up flagged as Ocean.
This PR's fix: before the new BFS pass, zero out every Ocean flag, so
only the truly-largest body at the current scale ends up marked.
It's incidental to the perf work but it's a real semantic change — the
on-disk .bin files will differ from main on any map where ocean splits
across downscaling. The PR doesn't mention it, which is why I flagged
it.

## Description:
Corrected inbalance in Luna map between top and bottom. Now both sides
have about equal land tiles.
Testing and editing was done to help boat-pathing at least look normal
along bottom half.
Additional notch cut in orbit lines to take edge off boat-pathing. Now
obstacle is almost a straight line.
Filled in center orbits to help players push easier. It was reported to
be tedious previously.
'Top Secret Military Base' nation was renamed with only vowels blacked
out for easier reading of joke name.
'Monolith' nation was renamed with a special character that displays
like the actual Monolith.

## Description:
Starting v32 maps right now!
Adds map of the Middle East. Probably one of the most highly requested
maps.
Very large map (3.4M land pixels, similar to Two Lakes, would become the
2nd or 3rd largest map by land area) of the arabian peninsula and
surrounding regions.
This map has both huge areas of land without water access full of desert
terrain, and massive trade chokepoints, which combined will result in
crazy endgames.
The theme of this map are historical, based on the end of WW1.
Historical flags have been added for the nation NPCs to use.
(High map rotation of 8 since this is probably going to become one of
the most popular maps given the relevancy of the region in real life.)

QoL changes for the Bosphorus map.
The base image for the map had a little aliasing which resulted in some
rivers being cut off.

/>
All of the nations except istanbul also had absolutely nothing to do
with the region. For example, Varna is a city in Northeast bulgaria and
the aegean isles are also nowhere near. There was also a nation that did
not spawn because its coordinates were in the sea.

All of these poor designs are probably the result of the map being
resized, originally being a larger map. It probably explains why this is
the smallest map by land area (not counting Oceania)
Fixes:
- Fixed landlocked rivers and added More accurate bodies of water
- Complete remake of the nations. Nations are now far more accurately
placed districts of the region, and more evenly placed

## Description:
Comprehensive accuracy and quality-of-life improvements across 8 maps.
No gameplay mechanics changed: only nation names, spawn positions, and
flag codes. All changes bring maps closer to real-world geographic and
historical accuracy.
**Changes by map:**
1. **North America:** Corrected numerous incorrect state spawn
positions. Added all 13 Canadian provinces and territories with correct
flags, as well as a few additional bots for balancing and completeness.
2. **South America:** Corrected spawn positions of Venezuela, Suriname,
and French Guiana. Added four Brazilian states (Amazonas, Pará, Bahia,
São Paulo) for better regional coverage and balancing.
3. **Gateway to the Atlantic:** Full historical consistency pass
targeting the ~1340-1410 CE period, matching the existing Britannia and
Italia map style. Renamed several nations for historical accuracy (Duchy
of Burgundy, Kingdom of Navarre, Kingdom of Majorca, City of Avignon,
Crown of Aragon, Duchy of Aquitaine, Hafsid Sultanate, Marinid
Sultanate, Zayyanid Sultanate, Holy Roman Empire). Added 7 new
historically accurate flag SVGs for these nations.
4. **Europe:** Shortened long-form nation names to short-form for
consistency with other maps. Added Andorra and Monaco for improved
balance.
5. **Europe Classic:** Fixed "Syrian Arab Republic" to "Syria" for
consistency with all other maps. Added Baltic states, Croatia, Denmark,
Sápmi for balancing.
6. **Oceania:** Removed ghost bots that no longer appear on the map.
Fixed truncated and outdated names: Lao PDR to Laos, Brunei Darussalam
to Brunei, TimorLeste to Timor Leste, Taiwan Province of China to
Taiwan.
7. **World:** Fixed outdated names for accuracy and consistency with the
World map and other maps. Added bots in regions lacking coverage for
more consistent global representation.
8. **Giant World Map:** Updated nation names for accuracy and
consistency. Added Canadian provinces, US states, Bolivia, and Gabon for
improved map balance.
All changes made and verified in the map editor. No en.json or UI
changes required as these are map data files only.

Small-island removal previously ran only on the full-size terrain. The
compact (4x downscaled) map inherited that filtering before being
downscaled, which meant islands that survived at full size could end up
as tiny specks in the compact map.
This PR runs `removeSmallIslands` on the 4x terrain as well, with half
the threshold (15 vs 30 tiles), so very small islands are pruned in
compact maps while the full-size map is unchanged.

/>
Because of mixed opinions about replacing the maps, i propose at least
this temporary compromise: Bering Sea gets added as a new map and Bering
Strait gets its rotation lowered to a small number. Since the classic
maps are probably being taken off rotation, we should have some small
breathing space for the 2 maps.
In the near future we should discuss between mapmakers in the dev server
whether we keep, replace or completely take Bering Strait off rotation,
and/or a community poll.

## Description:
This was a proposal in the map channel of the dev discord server:
**Updates the Europe map to include Iceland, and removes Classic Europe
off rotation.** Classic Europe will remain in custom private map list
The only thing the new europe map didnt have from the classic version
was iceland, so i figured we should update the europe map to contain it,
since Iceland is a popular spawn in the classic version. Iceland is in
the same position as the classic map
The classic europe is frankly a lesser version of the new map as it
doesnt contain rivers , is smaller and the terrain has less quality, and
with the updated version, classic would just take up very needed space
in the lobby queue. We currently have a very large number of maps, which
results in players having to wait for a long time for an specific map in
public lobbies. This should help the issue a little at the very least.
