initial: dungeon crawler with Bun + TypeScript modular architecture
- 19 TypeScript modules under src/ (constants, entities, room, game, render) - Canvas 2D rendering with dark fantasy palette - Room-based navigation, random 7x7 map generation - Two combat modes: ranged (pistol) and melee (knife) - Wall collision with door opening support - Minimap, HP bar, enemy AI - Bun build pipeline: src/main.ts -> dist/main.js + dist/index.html
