feat: add reorganize-music.sh to migrate genre folders to Artist/Album structure

Reads ffprobe metadata from every audio file and places it into:
  {dest}/{AlbumArtist}/{Album}/{NN - Artist - Title.ext}
Exactly mirrors the sanitize(), folder and filename rules in
backend/lib/ytdlp.js. Dry-run by default; --move to execute, --clean
to remove empty source dirs afterwards.
