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.

9b1eedc379 feat: Ableton Live-style effects and complete automation system 
Enhanced visual design:
- Improved device rack container with darker background and inner shadow
- Device cards now have rounded corners, shadows, and colored indicators
- Better visual separation between enabled/disabled effects
- Active devices highlighted with accent border

Complete automation infrastructure (Phase 9):
- Created comprehensive type system for automation lanes and points
- Implemented AutomationPoint component with drag-and-drop editing
- Implemented AutomationHeader with mode controls (Read/Write/Touch/Latch)
- Implemented AutomationLane with canvas-based curve rendering
- Integrated automation lanes into Track component below effects
- Created automation playback engine with real-time interpolation
- Added automation data persistence to localStorage

Automation features:
- Add/remove automation points by clicking/double-clicking
- Drag points to change time and value
- Multiple automation modes (Read, Write, Touch, Latch)
- Linear and step curve types (bezier planned)
- Adjustable lane height (60-180px)
- Show/hide automation per lane
- Real-time value display at playhead
- Color-coded lanes by parameter type
- Keyboard delete support (Delete/Backspace)

Track type updates:
- Added automation field to Track interface
- Updated track creation to initialize empty automation
- Updated localStorage save/load to include automation data

Files modified:
- components/effects/EffectDevice.tsx (Ableton-style visual improvements)
- components/tracks/Track.tsx (automation lanes integration)
- types/track.ts (automation field added)
- lib/audio/track-utils.ts (automation initialization)
- lib/hooks/useMultiTrack.ts (automation persistence)
