Sebastian Krüger 119c8c2942 feat: implement medium effort features - markers, web workers, and bezier automation ...

Implemented three major medium effort features to enhance the audio editor:

**1. Region Markers System**
- Add marker type definitions supporting point markers and regions
- Create useMarkers hook for marker state management
- Build MarkerTimeline component for visual marker display
- Create MarkerDialog component for adding/editing markers
- Add keyboard shortcuts: M (add marker), Shift+M (next), Shift+Ctrl+M (previous)
- Support marker navigation, editing, and deletion

**2. Web Worker for Computations**
- Create audio worker for offloading heavy computations
- Implement worker functions: generatePeaks, generateMinMaxPeaks, normalizePeaks, analyzeAudio, findPeak
- Build useAudioWorker hook for easy worker integration
- Integrate worker into Waveform component with peak caching
- Significantly improve UI responsiveness during waveform generation

**3. Bezier Curve Automation**
- Enhance interpolateAutomationValue to support Bezier curves
- Implement cubic Bezier interpolation with control handles
- Add createSmoothHandles for auto-smooth curve generation
- Add generateBezierCurvePoints for smooth curve rendering
- Support bezier alongside existing linear and step curves

All features are type-safe and integrate seamlessly with the existing codebase.
