feat: show real on-disk tracklist in the Library album modal (#9)
The Library modal showed MusicBrainz's canonical tracklist, hiding incomplete downloads / edition or track-order mismatches, and showed nothing for albums without an rgMbid. Now it shows the REAL files on disk. - LibraryItem gains trackNames String[] (migration add_library_track_names): the album's on-disk "## Title.ext" audio filenames. - Captured at import (pipeline._import lists the final album folder) and at scan (scan._record_owned now also refreshes trackNames on re-scan via ON CONFLICT DO UPDATE + xmax=0 to preserve the newly-imported flag). New shared library.list_audio_files() helper. - /api/library exposes trackNames; the AlbumModal prefers on-disk tracks when present (parsed "## Title" → position/title, zero network, labeled "On disk · N tracks"), falling back to the MusicBrainz listing otherwise. Items imported before this column show the MB fallback until re-scanned. worker 221 tests / 7-skip, web 153, tsc + build clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
