v1.1.0

### Scene System
- Scene = ordered cue list referencing presets with transitions (Cut, Dissolve, ParamMorph)
- SceneStore: save/load/delete scenes to `~/.config/phosphor/scenes/*.json`
- Timeline state machine: Idle → Holding → Transitioning with auto-advance and beat sync
- ParamMorph transitions: smooth interpolation of all params and layer opacities
- Dissolve transitions: GPU crossfade via fullscreen shader with snapshot capture
- Scene panel in left sidebar: cue list management, transport controls, save/load/delete
- Per-cue transition type editing: click to cycle Cut → Dissolve → Morph
- Per-cue transition duration editing via DragValue
- Advance mode selector: Manual / Timer / Beat Sync with per-cue hold times and beats-per-cue
- Auto-save: cue and timeline changes persist to disk immediately
- Timeline bar above status bar: cue blocks, playhead during hold and transitions, click-to-jump
- Scene status indicator (SCN) in status bar with cue counter
- Keyboard: Space (next cue), T (toggle timeline)
- MIDI triggers: SceneGoNext, SceneGoPrev, ToggleTimeline
- OSC: `/phosphor/trigger/scene_go_next`, `scene_go_prev`, `toggle_timeline`
- Web control: Prev Cue / Next Cue / Timeline trigger buttons
- MIDI Clock sync: parse 0xF8/FA/FB/FC system realtime, derive external BPM, beat-synced advance
- MIDI Clock → Timeline: auto-follow transport (play/stop), MIDI clock beats drive BeatSync mode with audio fallback
- OSC scene control: `/phosphor/scene/goto_cue`, `/scene/load` (int or string), `/scene/loop_mode`, `/scene/advance_mode`
- OSC outbound timeline state: `/phosphor/state/timeline/active`, `cue_index`, `cue_count`, `transition_progress` at TX rate

### UI
- Redesign scene panel: card-framed scene list, section headers (TRANSPORT / CUE LIST), sized transport buttons (PLAY ghost-border, STOP|PREV|GO), transition type badges with color per type, ghost-border "+ Cue" button
- Widen side panels from 270px to 315px
