track controls and waveform viewing.

Phase 9 Automation Improvements:
- Replaced multiple automation lanes with single lane + parameter selector
- Added dropdown in automation header to switch between parameters:
- Track parameters: Volume, Pan
- Effect parameters: Dynamically generated from effect chain
- Lanes are created on-demand when parameter is selected
- Effects panel now has fixed height (280px) with scroll
- Panel no longer resizes when effects are expanded
- Maintains consistent UI layout
Technical changes:
- Track.automation.selectedParameterId: Tracks current parameter
- AutomationHeader: Added parameter dropdown props
- AutomationLane: Passes parameter selection to header
- Track.tsx: Single lane rendering with IIFE for parameter list
- Effects panel: h-[280px] with flex layout and overflow-y-auto

- 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.

Major improvements:
- Fixed multi-file import (FileList to Array conversion)
- Auto-select first track when adding to empty project
- Global effects panel folding state (independent of track selection)
- Effects panel collapsed/disabled when no track selected
- Effect device expansion state persisted per-device
- Effect browser with searchable descriptions
Visual refinements:
- Removed center dot from pan knob for cleaner look
- Simplified fader: removed volume fill overlay, dynamic level meter visible through semi-transparent handle
- Level meter capped at fader position (realistic mixer behavior)
- Solid background instead of gradient for fader track
- Subtle volume overlay up to fader handle
- Fixed track control width flickering (consistent 4px border)
- Effect devices: removed shadows/rounded corners for flatter DAW-style look, added consistent border-radius
- Added border between track control and waveform area

Fixed layout issues with the level meter:
Track Height:
- Increased DEFAULT_TRACK_HEIGHT from 150px to 180px
- Ensures enough vertical space for all controls without clipping
Level Meter Display:
- Now always visible (not conditional on recording state)
- Shows "Input" with mic icon when track is armed or recording
- Shows "Level" with volume icon when not recording
- Displays appropriate level based on state
This prevents the meter from being cut off and provides consistent
visual feedback for all tracks. Future enhancement: show actual
playback output levels when not recording.

Increased DEFAULT_TRACK_HEIGHT from 120px to 150px to properly fit:
- Volume slider
- Pan slider
- Input level meter (when track is armed or recording)
This ensures all controls have adequate vertical spacing and the input
meter doesn't get cramped when it appears under the pan control.

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.

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.
