Introduce a complete Craps implementation featuring a Phaser-based UI,
deterministic game logic, and heuristic AI players.
Key changes:
- CrapsLogic.js: Pure-state rules engine handling Pass/Don't Pass, Place,
Come/Don't Come, Field bets, odds, and full resolution logic.
- CrapsAI.js: Stateless AI personalities (conservative, balanced, aggressive,
gambler) derived from player names to drive betting behavior.
- CrapsGame.js: Phaser scene with animated dice rolls, chip tray, dynamic
bet zones, portrait-based opponents, and persistence via profile API.
- Wire Craps into the game registry, main scene loader, and GameRoom dispatcher.
- Remove Socket.IO dependency, server multiplayer logic (lobby, room management), and client-side socket service
- Replace multiplayer-only flow with single-player AI gameplay; add `OpponentSelectScene` for AI configuration
- Simplify game registry to use `minOpponents`/`maxOpponents` instead of `supportsMultiplayer`/`multiplayerOnly`
- Update game registration to remove multiplayer flags and adjust `games` table schema to hardcode `supports_multiplayer = 0`
- Remove `SOCKET_IO_CORS_ORIGIN` from environment configuration
- Update documentation to reflect single-player architecture and simplified game creation process
- Fix minor UI issues: add width to buttons in auth scenes, fix auth listener cleanup in LandingScene, restore DOM layer visibility in Modal
