Supersedes #3143
This PR introduces "ghost railways": when you are going to place a city
or port, previews railway connections that will be made when actually
building the structure.
Ghost railways are skipped if the structure is going to be snapped to
existing railways (as in railway snapping functionality introduced in
#3156 ).

## Description:

The `RailroadLayer` simply displays tiles as instructed by the core
worker. While it's practical for the layer to only care about the tiles,
it also means it has no understanding of railroads as entities (their
paths, connections, or identities).
It also means that the core worker is responsible for rendering tasks
such as tile orientation and construction animation, which is not
expected.
To support ID-based events and better separation of concerns, the
rendering layer needs to be aware of complete railroads. With this
change, the core worker can send the tiles once and subsequently
reference railroads only by ID for all other events.
#### Changes:
- `RailroadLayer` now stores full railroad data instead of only
individual tiles
- `RailroadLayer` is responsible for animating newly built railroads
- Add a new `RailroadSnapUpdate` sent when a new structure is built over
an existing railroad. This event is used by `RailroadLayer` to keep
railroad ID in sync.
- When hovering over a railroad, the render worker is querying the core
worker about overlapping railroads.
Alternatively, RailroadLayer could compute overlaps itself now that it
has full railroad knowledge, but this logic would need to be duplicated
and kept in sync across workers. Keeping a single source of truth in the
core worker is preferred.
#### Edgecases:
- When a structure snaps over a railroad, the original railroad is split
into two new railroads. If the construction animation is still in
progress, instead of resuming the animation at the correct point on the
new railroads, all remaining tiles are rendered immediately
- Previously, `RailroadUpdate` handled both construction and
destruction. This no longer works with `RailroadSnapUpdate`, as event
ordering is now pretty important and IDs may be lost before they are
consumed.
To address this, RailroadUpdate is split in two:
`RailroadConstructionUpdate` and `RailroadDestructionUpdate`.

## Description:
Adds network bright green highlighting to Railway tracks connecting
_your_ factories and buildings together when in the alternate view
(spacebar view). It is sometimes hard to see your own tracks on certain
areas of the map (mountain terrains for example), so this change will
highlight the tracks the same color as your border outline in the
alternate view (#00FF00). Also suggested by [this
comment](https://discord.com/channels/1284581928254701718/1445984695752855562/1445984695752855562)

## Description:
This PR addresses issue #2302: where there is no obvious information
about the self-player's team during the spawn phase of the game.
Currently, during TEAM games (where there is a set number of teams
defined), the self player's spawn highlight color is white, while all
other players are shown with a team-based spawn highlight color. This
makes it difficult to discern who is a teammate, especially since the
current live version (v0.26.7) uses green/yellow for other players to
depict teammate/other team, respectively.
Technically, the same is true for Duos, Trios, and Quads games, although
this has been addressed separately with PR #2298 by reverting to
green/yellow for teammate/other team players.
This PR changes the color of the self player's breathing spawn highlight
ring to match their assigned team color (with `alpha=0.5` for
transparency). The breathing ring is semi transparent on top of the
existing white static semi-transparent ring, giving the breathing ring a
**tint** of the team color instead of the exact team color.
This allows a player to immediately identify their assigned team and
maintains overall consistency with FFA, Duos, Trios, and Quads game
modes.
See below for example implementation. In this screenshot, the self
player is on the red team as shown by the red tint to the breathing
spawn highlight ring. The screenshot also shows some of the static white
semi-transparent ring around the spawn location. The self player's
teammate is to the top left of the image with a solid red spawn
highlight. The non-player (nation) opponent on the blue team is shown to
the bottom left. In online games, nations are not present in team games.
In single player or private lobby games they are shown as here, without
a spawn color highlight and only a territory color.

### ✅ Summary of Changes
This PR enables the ESLint rule **`@typescript-eslint/no-unused-vars`**
as requested in the issue and applies the necessary code adjustments
across the project.
#### 🔧 What was done:
- Activated the rule `@typescript-eslint/no-unused-vars` in the ESLint
config.
- Updated ~70 files to comply with the rule:
- Replaced unused variables with a `_` prefix where appropriate.
- Added inline ESLint disable comments (`eslint-disable-next-line`) for
specific cases where the variable or code block seemed important for
context, readability, or future use.
- Ensured no linting errors remain related to this rule.
---
### ❓ Clarification
Some cases were handled with inline disable comments instead of removing
the variable entirely, to avoid accidental breaking changes or loss of
intent.
If a different approach is preferred (e.g., stricter removal or
alternative handling), I’m happy to adjust the implementation
accordingly — just let me know!
---
### 🙌 Next Steps
Please review and let me know if:
- Any file should be handled differently.
- You prefer removal instead of disabling in certain areas.
- Additional rules should be enforced or reverted.
I’m available to make any follow-up improvements needed.

## Description:
Add support for colored territory patterns/skins
* Refactored & updated territory pattern rendering to render colored
skins
* rename public from pattern to skin (keep pattern name internally, too
difficult to rename)
* Moved all territory color logic to PlayerView
* Updated WinModal to show colored skins
* Refactored decode logic into a separate function: decodePatternData
* Refactored/updated how cosmetics are sent to server. Players now send
a PlayerCosmeticRefsSchema in the ClientJoinMessage.
PlayerCosmeticRefsSchema just contains names of the cosmetics, and the
server replaces the names/references with actual cosmetic data
* Refactored PastelThemeDark: have it extend Pastel theme so duplicate
logic can be removed.

Connect stations over water by automatically building bridges
Changes:
- Railroad construction to water is allowed from shore lines
- Railroad construction from water is allowed to shore lines too
This creates bridges a few tiles long.

## Description:
Add a rail network to handle train stations/railroad between structures.
Changes:
- `RailNetwork` is responsible for the train station graph. Use it to
connect new `TrainStations`
- A `RailRoad` connects two `TrainStation`
- No loop possible in the rail network
- Train stations handles its railroads
- Added a layer to draw the railroads under the structures
#### Clusters
- To speed up computations, each `TrainStation` references its own
cluster
- A cluster is a list of `TrainStation` connected with each other,
created by the `RailNetwork` when connecting the station
- Train stations spawn trains randomly depending on its current cluster
size
- A `TrainStation` decides randomly of the train destination by picking
one from the cluster
#### Production building:
- Added a factory which has no gameplay impact currently. _To be
discussed._
#### Train stops:
- When a train reaches a factory, it's filled with a "cargo". The loaded
trains has no impact currently. _To be discussed._
- When a train reaches a city, the player earn 10k gold
- When a train reaches a port, it sends a new tradeship if possible
- If a destination/source is destroyed, the train & railroad are deleted
too
