Major UX refactor to match professional DAW workflows (Ableton/Bitwig):
**Layout Changes:**
- Removed sidebar completely
- Track actions moved to header toolbar (Add/Import/Clear All)
- Each track now shows its own devices/effects in the track strip
- Master section moved to bottom footer area
- Full-width waveform display
**Track Strip (left panel):**
- Track name (editable inline)
- Color indicator
- Collapse/Solo/Mute/Delete buttons
- Volume slider with percentage
- Pan slider with L/C/R indicator
- Collapsible "Devices" section showing track effects
- Shows effect count in header
- Each effect card shows: name, enable/disable toggle, remove button
- Effects are colored based on enabled/disabled state
- Click to expand/collapse devices section
**Master Section (bottom):**
- Transport controls (Play/Pause/Stop) with timeline
- Master volume control
- Master effects placeholder (to be implemented)
**Benefits:**
- True DAW experience like Ableton Live
- Each track is self-contained with its own effect chain
- No context switching between tabs
- Effects are always visible for each track
- More screen space for waveforms
- Professional mixer-style layout
Note: Effects are visible but not yet applied to audio - that's next!
