feat: add Phase 6.6 Effect Chain Management system
Effect Chain System: - Create comprehensive effect chain types and state management - Implement EffectRack component with drag-and-drop reordering - Add enable/disable toggle for individual effects - Build PresetManager for save/load/import/export functionality - Create useEffectChain hook with localStorage persistence UI Integration: - Add Chain tab to SidePanel with effect rack - Integrate preset manager dialog - Add chain management controls (clear, presets) - Update SidePanel with chain props and handlers Features: - Drag-and-drop effect reordering with visual feedback - Effect bypass/enable toggle with power icons - Save effect chains as presets with descriptions - Import/export presets as JSON files - localStorage persistence for chains and presets - Visual status indicators for enabled/disabled effects - Preset timestamp and effect count display Components Created: - /lib/audio/effects/chain.ts - Effect chain types and utilities - /components/effects/EffectRack.tsx - Visual effect chain component - /components/effects/PresetManager.tsx - Preset management dialog - /lib/hooks/useEffectChain.ts - Effect chain state hook Updated PLAN.md: - Mark Phase 6.6 as complete - Update current status to Phase 6.6 Complete - Add effect chain features to working features list - Update Next Steps to show Phase 6 complete 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
