feat: add Balatro — poker roguelike game
Implement a complete Balatro clone with:
- Pure logic engine (BalatroLogic.js): seeded RNG, ante/blind state machine,
shop, consumables, boss-blind hooks, save/load, endless mode
- Scoring pipeline (BalatroScoring.js): full poker evaluator (including secret
hands, wilds, stones, smeared/fourFingers/shortcut passives) and chips×mult
trace for deterministic scoring animation
- 114 Joker definitions with rich effect hooks (onScored, onHeld, independent,
cardRetriggers, scaling state, copy via Blueprint/Brainstorm)
- 22 Tarots, 12 Planets, 15 Spectrals, 8 decks, 16 vouchers, 10 booster pack
types, 20 boss blinds + 3 finishers
- Phaser scene with procedural card/Joker rendering, art-frame drop-in support,
melty swirl background shader, and trace-based replay animation
- Headless verification suite (tools/verifyBalatro.js) with evaluator table
tests, scoring goldens, 200-bot smoke test, determinism & mid-run serialize
round-trip checks, and endless scaling tests
- Tutorial text and sprite-sheet layout documentation
