feat: complete rebuild — all 16 phases, modular game engine

- Phase 0: Core engine (scene manager, store, bus, net, tween, audio, canvas, HUD, i18n)
- Phase 1: Auth (splash, login, register, token management)
- Phase 2: Play World (game carousel, mode picker, bot/time selectors, queue)
- Phase 3-4: Chess (canvas board, drag/drop, chess.js, Stockfish bots, clock, live matchmaking)
- Phase 5: Domino (tile chain logic, bot AI, pip scoring, multiplayer)
- Phase 6: Ludo (cross-board, dice, captures, 4-player bots)
- Phase 7: Social (friends, notifications, realtime)
- Phase 8: Organizations (browse, join, members, detail)
- Phase 9: Rewards (daily claims, streak, coins)
- Phase 10: Profile (player card, stats, settings, logout)
- Phase 11: Shop (cosmetics, purchase flow, equip)
- Phase 12: Rank (leaderboard, tournaments, registration)
- Phase 13: Puzzles (chess training with rating)
- Phase 14-16: All APIs, polish, deployment config
