This commit resolves several physics-related issues that were causing
unexpected behavior in ship and asteroid movement:
**Physics Sleep System**
- Fixed abrupt stops by preventing Havok from putting bodies to sleep
- Added PhysicsActivationControl.ALWAYS_ACTIVE for ship and asteroids
- Made ship sleep behavior configurable via shipPhysics.alwaysActive
- Sleep was causing sudden velocity zeroing at low speeds
**Center of Mass Issues**
- Discovered mesh-based physics calculated offset CoM: (0, -0.38, 0.37)
- Override ship center of mass to (0, 0, 0) to prevent thrust torque
- Applying force at offset CoM was creating unwanted pitch rotation
- Added debug logging to track mass properties
**Input Deadzone Improvements**
- Implemented smooth deadzone scaling (0.1-0.15 range)
- Replaced hard threshold cliff with linear interpolation
- Prevents abrupt control cutoff during gentle inputs
- Added VR mode check to disable keyboard fallback in VR
**Configuration System**
- Added DEFAULT_SHIP_PHYSICS constant as single source of truth
- Added tunable parameters: linearDamping, angularDamping, alwaysActive
- Added fuel consumption rates: linearFuelConsumptionRate, angularFuelConsumptionRate
- Tuned for 1 minute linear thrust, 2 minutes angular thrust at 60Hz
- All physics parameters now persist to localStorage
**Other Fixes**
- Changed orbit center to STATIC motion type (was ANIMATED)
- Fixed linear force application point (removed offset)
- Added ship initial velocity support from level config
- Changed physics update from every 10 frames to every physics tick
- Increased linear input threshold from 0.1 to 0.15

Added stateKey field to VoiceMessage interface to explicitly link messages
with warning states, preventing infinite repeat loops.
Bug fixes:
- Messages check warning state exists before re-queuing
- clearWarningState() now purges matching messages from queue
- Proper cleanup when resources increase above thresholds
Changes to voiceAudioSystem.ts:
- VoiceMessage interface: Added stateKey field
- queueMessage(): Added stateKey parameter
- handleStatusChange(): Pass state keys when queueing warnings
- update(): Validate state exists before re-queuing repeating messages
- clearWarningState(): Filter queue to remove messages with matching stateKey
Also includes explosion audio improvements:
- Use onEndedObservable instead of setTimeout for audio cleanup
- Adjusted explosion force and duration parameters

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
