- Added showEffects property to Track type
- Added "E" button with Sparkles icon to toggle per-track effects
- Effects panel now appears below each track when toggled
- Removed global EffectsPanel from AudioEditor
- Updated useMultiTrack to persist showEffects state
- Streamlined workflow: both automation and effects are now per-track
This aligns the UX with professional DAWs like Ableton Live, where
effects and automation are track-scoped rather than global.

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.

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.
