feat: complete Phase 4 combat/hunting system
- Add content migration (003_content.sql): zones, monsters, items, loot tables - Add inventory migration (004_inventory.sql) and logs migration (006_logs.sql) - Add Mulberry32 PRNG (src/utils/rng.js) for deterministic combat - Add combat system (src/game/combat.js) with turn order, crit, mage bonus, 20-round cap - Add rewards/loot system (src/game/rewards.js) and leveling (src/game/leveling.js) - Add hunt endpoint (POST /api/hunt) with full combat flow in DB transaction - Add hunt integration tests and unit tests for rewards/leveling/combat - Fix session middleware to use memory store in tests (avoids cleanup hang) - Fix huntService transaction (db.transaction() returns wrapper, must call separately) - Add huntService to helpers.js cache invalidation for test isolation
