Introduce a new single-player logic puzzle game where players flick jelly
blobs across a grid to slide and merge them into a single monster.
- PuddingMonstersLogic.js: pure slide-and-merge model with BFS solver,
no Phaser/DOM dependencies; shared by client and generator
- PuddingMonstersGame.js: Phaser scene with drag-to-flick, arrow keys,
undo/reset/hint, par tracking, star collection, death on spikes
- genPuddingMonsters.js: offline level generator using seeded RNG and
BFS solver; produces 40 levels across 5 difficulty tiers
- puddingmonsters.json: generated level data (40 levels, 5–7 grid sizes)
- Update main.js, GameRoomScene.js, PreloadScene.js, registry.js to
wire the new game into the app
- Update game-icons assets
