Performance optimizations and audio quality improvements

🎵 Audio Fixes:
- Fixed 'Unable to load asset' errors by updating pubspec.yaml
- Switched from compressed mono to high-quality stereo audio files
- Added ambient_background.mp3 to source directory for consistency
- Background music: 2.8MB stereo vs 704KB compressed (4x quality improvement)

⚡ Performance Optimizations:
- Optimized timer text updates (60 FPS → 1 FPS when seconds change)
- Reduced particle effects from 16 to 8 particles with shorter duration
- Simplified background animations (3 layers → 2, slower controllers)
- Added bubble caching to avoid expensive component searches
- Optimized shake effects using cached bubble references

📊 Results:
- Significantly reduced frame drops (fixes 'Skipped frames' warnings)
- Lower memory usage from optimized particle cleanup
- Smoother gameplay with maintained audio/haptic feedback
- Better user experience with high-quality stereo sound
