feat(node): Music app node-side — indexing, MusicBrainz enrichment, protocol

2026-08-24T15:12:36Z

Implements the node half of docs/musicbay.md against MNP 0.8: - IndexEntry gains artist/album/track_no (reuses duration/thumb_hash/ display_title, already generic). New musicbrainz_config/_enabled and music_meta_req/_resp message pairs, mirroring the TMDB shape. - title_parse.parse_track_filename: track-number-prefix + title parsing, fallback-only (embedded tags are the primary source, unlike Videos). - indexer.enrich_audio.AudioEnricher: mutagen-based tag/embedded-cover extraction through its own bounded pool (asyncio.to_thread, no subprocess — no ffmpeg-shaped deadlock risk). Gated on "music" in a group's enabled_apps rather than a video_root-style scoped folder. - musicbrainz.py: MusicBrainzClient — no API key (unlike TMDB), just a self-imposed ~1 req/s pace and a configurable, non-default User-Agent contact string; inert (no calls at all) when no contact is configured, never sends an unidentified client. - media_cache.py: file_mbid/mbid_meta tables alongside the existing TMDB ones, cover art reusing the thumbs table via a synthetic musicbrainz:{mbid} id, pruned on file deletion. - roster.py/ops.py/webrtc_server.py: musicbrainz_contact (node-wide) and musicbrainz_enabled (per-group, from the start) as signed operator settings, ALLOWED_APPS gains "music", _do_music_meta_request resolves and caches a release-level MusicBrainz match per (artist, album). - daemon.py: AudioEnricher/MusicBrainzClient wired alongside the video ones; a group's existing library is swept when "music" is newly enabled (no video_root equivalent — see musicbay.md §2.1). 41 new tests (musicbrainz.py against a mocked transport, admin-op policy for both new settings, media_cache round-trip/pruning, enrich_audio end-to-end against real ffmpeg-generated MP3s). Full suite (common + node + hub): 1116 passed, no regressions. Client-side (music-app.js, persistent player bar) not started yet.
