feat: complete Phase 9.3 - automation recording with write/touch/latch modes
Implemented comprehensive automation recording system for volume, pan, and effect parameters: - Added automation recording modes: - Write: Records continuously during playback when values change - Touch: Records only while control is being touched/moved - Latch: Records from first touch until playback stops - Implemented value change detection (0.001 threshold) to prevent infinite loops - Fixed React setState-in-render errors by: - Using queueMicrotask() to defer state updates - Moving lane creation logic to useEffect - Properly memoizing touch handlers with useMemo - Added proper value ranges for effect parameters: - Frequency: 20-20000 Hz - Q: 0.1-20 - Gain: -40-40 dB - Enhanced automation lane auto-creation with parameter-specific ranges - Added touch callbacks to all parameter controls (volume, pan, effects) - Implemented throttling (100ms) to avoid excessive automation points Technical improvements: - Used tracksRef and onRecordAutomationRef to ensure latest values in animation loops - Added proper cleanup on playback stop - Optimized recording to only trigger when values actually change 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
