Refactor: Move explosion sound to ExplosionManager

Moved explosion audio management from RockFactory to ExplosionManager for better separation of concerns and synchronized audio/visual effects.

Changes:
- ExplosionManager: Added audio support with sound pooling (5 instances)
  - New initAudio() method to load explosion sounds after audio unlock
  - Sound pool prevents concurrent explosion conflicts
  - Spatial audio synchronized with visual duration (1000ms)
  - Proper SoundState checking for available sounds

- RockFactory: Simplified by delegating audio to ExplosionManager
  - Removed _explosionSound and _audioEngine properties
  - initAudio() now delegates to ExplosionManager
  - Collision callback reduced from ~60 to ~30 lines
  - Fixed disposal order to prevent double-disposal errors

Benefits:
- Fixes concurrent explosion sound bug (multiple asteroids can explode simultaneously)
- Audio/visual timing synchronized (both use config.duration)
- Cleaner code organization (all explosion effects in one place)
- Proper disposal ordering prevents runtime errors
