Update gameplay mechanics, asteroid model, and star base physics

- Switch to asteroid4.glb model with updated material handling
- Adjust difficulty parameters: increased spawn distances (220-450m range), updated force multipliers, varied asteroid sizes
- Fix scoreboard timer display (was showing frames instead of actual seconds)
- Refactor star base to use asset container with mesh merging for better performance
- Change star base physics from STATIC to ANIMATED with collision detection enabled
- Add directional lighting in level deserializer for improved scene lighting
- Clean up commented code and optimize debug logging
- Update base.glb 3D model
