fix: resolve 7 circular dependency chains in src/lib/game

- equipment/utils.ts: import directly from individual equipment modules instead of index.ts
- golems/utils.ts: import directly from individual golem modules instead of index.ts
- combatStore.ts: extract CombatState to combat-state.types.ts, remove debugSetTime (was only user of gameStore import)
- combat-actions.ts: import CombatState from combat-state.types.ts instead of combatStore
- stores/index.ts: re-export CombatState from combat-state.types.ts
- GameStateDebug.tsx: replace debugSetTime calls with direct useGameStore.setState()

Verification: bunx madge --circular src/lib/game → No circular dependency found!
