N/A — maintainer refactor.
## Description:
Makes each map's `info.json` the single source of truth for map metadata
— adding a map is now a folder with `image.png` + `info.json`, a
`gen-maps` run, and an en.json display name.
**info.json / manifest.json carry full map metadata.** Every
`map-generator/assets/maps/<map>/info.json` declares `id` (the
`GameMapType` enum key), `name` (the enum value — wire format, unchanged
for all 94 maps), `translation_key`, `categories`, and
`multiplayer_frequency` (the public-playlist weight that used to be the
`FREQUENCY` record in MapPlaylist.ts). The generator validates
everything and mirrors it into `resources/maps/<map>/manifest.json`. 23
stale info.json `name` values were normalized to the canonical enum
value; enum values are byte-identical, so replays and stored game
configs are unaffected.
**The generator emits the TypeScript and discovers maps itself.** New
`map-generator/codegen.go` generates `src/core/game/Maps.gen.ts`
(`GameMapType`, `GameMapName`, `mapCategories`, `mapTranslationKeys`,
`multiplayerFrequency` — now a full `Record<GameMapName, number>`,
killing the old `Partial`) on every run; `Game.ts` re-exports it. The
hardcoded map registry in `main.go` is gone — maps are auto-discovered
from the `assets/maps` / `assets/test_maps` directories. MapConsistency
tests fail with a "run `npm run gen-maps`" message if info.json,
manifest.json, and Maps.gen.ts drift. The tracked
`map-generator/map-generator` binary is rebuilt to match.
**New categories: continents + world/cosmic/tournament/other,
multi-category support.** `continental`/`regional`/`fantasy`/`arcade`
are replaced by `featured`, `world`, `europe`, `asia`, `north_america`,
`africa`, `south_america`, `oceania`, `antarctica`, `cosmic`,
`tournament`, and `other`. Maps can list multiple categories, so
straddlers (Black Sea, Bosphorus, Caucasus, Between Two Seas, Bering
Sea/Strait, Mena, Strait of Gibraltar, Hawaii, Arctic) appear under both
regions. Featured is itself a category (same 7 maps as before).
MapPlaylist keeps its arcade exclusion via an explicit set.
**Map picker UI.** Two tabs: **Featured** (default — featured maps plus
a Favorites section when maps are starred) and **All** (one prominent
collapsible bar per category with a map count, collapsed by default).
The selected map is prepended to the featured grid when it lives
elsewhere. `getMapName()` resolves through the generated
`mapTranslationKeys`, which also fixes tourney maps never resolving a
valid translation key.

## Description:
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.

## Description:
Similar to how Europe classic was taken off rotation, we do the same
with Britannia. The newer Britannia was slightly updated to include the
rivers of the classic version, this is because of feedback from players
in the discord server who say the rivers in the classic version are an
important part of gameplay. Map otherwise keeps same nations and size.

## Description:
- Add a test to ensure an error is thrown when manifest.json specifies a
non-existent flag.

## Description:
This PR removes the nation strength. Reasoning:
- It is currently unused. The backstory can be found in #2498
- It forces map-makers to do balancing work, which is probably not a
good idea
- It increases map-making work
- It increases nation balancing complexity by a lot (we need to have all
the json files in mind)
- It makes humans avoid map areas completely because there is always
that one, same, strong nation
- The map lead Nikola123 wants to "not deal with the stupid nations and
their balancing"
If the goal of nation strength was to make them feel different I would
suggest a nation personality system. Nations that love to boat, love to
ally, love to nuke, love to fullsend, etc.

## Description:
Move map generation outside of main repo, it has been rewritten in Go
and is much faster. Also refactor how maps are stored, one dir per map.
The map binaries are basically identical to before. Some maps like
Africa have 1% difference in bytes, but playing it looks exactly the
same.
Use lazy loading for map data access so only needed files are accessed.
Unit tests now load map binary instead of regenerating it from scratch,
speeding them up.
