First Library Management feature. On the Library album modal, "Delete album" (two-step confirm) removes the album: - deletes the folder on disk (guarded to only ever remove a path strictly inside the library root, LYRA_LIBRARY_ROOT, default /music), - drops the LibraryItem, - sets the matching MonitoredRelease monitored=false + currentQualityClass=null so the monitor won't immediately re-download it (re-Want later to restore). Requires the web container to see the library, so docker-compose now bind-mounts MUSIC_DIR at /music (rw) for web too. New DELETE /api/library/[id] (auth-gated, path-guarded). web 157 tests (delete happy-path + 404 + outside-root guard). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
