Three changes from the network-drive audit:
1. Delete-ordering fix. Deleting a media item cascades its annotations,
so the delete must never proceed while the item's library storage is
unreachable — the DB row died, the file survived as an orphan, and
the next scan re-imported it bare (annotations gone forever).
resolveMediaStorage stats the library's folders: reachable → delete
proceeds and the file is removed by ABSOLUTE path (the old code
passed a library-relative path to os.Remove, which never resolved —
file deletion has been a silent no-op); every folder unreachable →
409 with 'storage unreachable', row and annotations intact.
2. Latency: resolveLibrary stats every library folder on every SSR
render; folder reachability is now cached with a 30s TTL.
3. README: Network Storage section documenting the outage hysteresis
(mark → archive → auto-restore), the 90-day retention purge
(ARCHIVE_RETENTION_DAYS, 0 = never), refused deletes while storage
is down, and watch mode not firing on network mounts.
Integration tests: storage-down bulk delete refuses with the row
intact; real-file delete removes the file from disk.
