fix(node): the Music app's tags survive a restart

media_cache held video_meta, photo_meta and thumbs; the audio tags lived
only in the in-memory IndexEntry. So every start re-read every audio file
the node serves, and until that pass landed it served an index with no
artist on any track — one the Music app cannot group. Over a real
6176-file library the pass costs 27.8s cold and 6.4s from audio_meta.

Only what the bytes decided is stored. The filename and folder fallbacks
still run live, or a renamed file would get the old name's answer; the
sibling-cover scan reads the folder, so it stays live too; and a read
that failed is not cached, or one bad read becomes permanent.
