74879a42cf feat: implement multi-track waveform selection and editing with undo/redo
Added comprehensive selection and editing capabilities to multi-track editor:
- Visual selection overlay with Shift+drag interaction on waveforms
- Multi-track edit commands (cut, copy, paste, delete, duplicate)
- Full keyboard shortcut support (Ctrl+X/C/V/D, Delete, Ctrl+Z/Y)
- Complete undo/redo integration via command pattern
- Per-track selection state with localStorage persistence
- Audio buffer manipulation utilities (extract, insert, delete, duplicate segments)
- Toast notifications for all edit operations
- Red playhead to distinguish from blue selection overlay

All edit operations are fully undoable and integrated with the existing
history manager system.

f640f2f9d4 feat: implement per-track and master effect chains (Option 3)
Architecture:
- Each track now has its own effect chain stored in track.effectChain
- Separate master effect chain for the final mix output
- SidePanel has 3 tabs: Tracks, Track FX, Master FX

Changes:
- types/track.ts: Add effectChain field to Track interface
- lib/audio/track-utils.ts: Initialize effect chain when creating tracks
- lib/hooks/useMultiTrack.ts: Exclude effectChain from localStorage, recreate on load
- components/editor/AudioEditor.tsx:
  - Add master effect chain state using useEffectChain hook
  - Add handlers for per-track effect chain manipulation
  - Pass both track and master effect chains to SidePanel
- components/layout/SidePanel.tsx:
  - Update to 3-tab interface (Tracks | Track FX | Master FX)
  - Track FX tab shows effects for currently selected track
  - Master FX tab shows master bus effects with preset management
  - Different icons for track vs master effects tabs

Note: Effect processing in Web Audio API not yet implemented.
This commit sets up the data structures and UI.

cf1358e051 fix: ensure track name is always a string in createTrack
Added type checking to prevent event objects from being used as track names.
When onClick handlers pass events, we now explicitly check for string type.
