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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
