This update adds a full Library Tools suite plus CSV/JSON playlist import and export.

• Library Tools: scan your whole library at once from Multiple Playlist Actions — find duplicate songs and duplicate playlists, dead (unplayable) tracks, orphaned songs, empty or oversized playlists, and explicit content, plus a genre/era/play-count breakdown of your library.
• Consolidate multiple playlists into one, or remove a song from every playlist it's in, in a single pass.
• Export any playlist to CSV or JSON, and import one back in — matched against your library and Apple Music's catalog.
• On iPad, drag and drop a CSV or JSON file straight onto the Playlists tab to import it.
