Add ordered, timed sequences of scene presets that auto-cycle — activating
each preset and holding it for its dwell duration before advancing.
Backend:
- ScenePlaylist / PlaylistItem models + SQLite store (new scene_playlists table)
- PlaylistEngine: cycles ONE playlist at a time (starting one stops any other),
loop/shuffle, re-reads the playlist each cycle so edits/deletes apply at the
boundary, skips missing presets, guards against busy-loops; reuses the shared
apply_scene_state path used by scene presets and automations
- REST API: CRUD + /start, /stop, /state with scene-preset reference validation
- Constructed in the app lifespan with a bounded stop on shutdown
Frontend:
- New "Playlists" sub-tab in the Automations tab with start/stop controls and a
running indicator; editor modal with ordered scene rows (reorder + per-item
duration), loop/shuffle toggles, and tags
- Live refresh via the playlist_state_changed WebSocket event
- i18n in en/ru/zh
Tests: new unit + API coverage for the store/model, engine (cycling,
single-active exclusivity, missing-preset skip, shuffle, and the
playlist_state_changed event contract), and routes. Full suite green;
ruff and tsc clean.
