DJ USB Tkit 0.1.4

• Missing library source folders are now surfaced as recoverable UI state
  instead of being treated as deleted media during scan. Missing source chips
  render as warning chips, scan pruning ignores missing roots, and affected
  exports are blocked until the source is relocated or explicitly removed.
• Add source-root relocation for moved music folders. Relocation rewrites
  indexed track paths to the new folder while preserving track IDs and local
  playlist membership.
• Fix "Duplicate PDB entries" diagnostics failures that the offered strict
  parity repair could not actually resolve. Some playlists on
  long-lived, heavily-edited USBs had accumulated stale duplicate copies of
  a track's playlist membership in the device-side database; running the
  repair reported success without removing them. The repair now finds and
  removes the stale duplicates so affected playlists pass diagnostics.
• Fix strict parity reporting for playlist sort-order drift. eDB playlist
  sequence numbers that no longer match the device-facing PDB playlist order
  are now reported as ordering parity failures and routed through strict
  repair, which syncs eDB order back from PDB.
• Clicking a track row in a USB playlist or history list to load its
  waveform/BPM/key no longer rebuilds and repaints the entire visible track
  list — only the clicked row updates now, matching how the library view
  already behaves.

DJ USB Tkit 0.1.3

• Fix USB export becoming permanently blocked with a "PDB export blocked"
  error once a USB's playlist list had grown large enough to need extra
  internal storage space for a new playlist — affected any USB that had
  accumulated enough playlists over time, making it impossible to export any
  further new playlist to it.
• Fix USB diagnostics permanently reporting one unfixable "history page
  shape" issue on USBs with a single-entry history-menu page; repair now
  correctly recognizes it as already valid.
• Internal: clean up clippy lint warnings and apply cargo fmt across the
  backend and desktop crates (no functional changes).
• Detect WAV files using the WAVE_FORMAT_EXTENSIBLE header, which some
  Pioneer CDJs reject even when the underlying audio is otherwise within
  spec. Flagged during library scan with a format-badge tooltip; when the
  extensible header wraps plain PCM/IEEE-float data, export automatically
  rewrites it to a standard header (lossless, no re-encoding) so the file
  plays on CDJ hardware.

DJ USB Tkit 0.1.2

• Fix CDJ hardware hangs on pathological Unicode metadata (long
  combining-mark "zalgo" stacks and names mixing many unrelated Unicode
  scripts) in exported titles, artist, and album names, and in on-disk
  export file/folder names. Thanks to 00000ooooo's album "–5"
  (https://00000ooooo.bandcamp.com/album/--5) for the real-world torture
  test.
• Fix a MIPS unaligned-read hardware freeze for non-ASCII album names.

Note: while testing against that album, rekordbox threw an
"unexpected error" and broke playlists on export of the same USB.

DJ USB Tkit 0.1.1

• Fix macOS master.db detection for current rekordbox installs, which store
  the database directly under ~/Library/Pioneer/rekordbox/master.db rather
  than under Application Support.

DJ USB Tkit 0.1.0

• Initial public release.
• Local-first library scanning, playlist management, native playback, and
  frontend source-folder workflows.
• USB import/export with mirror and additive playlist sync modes.
• USB diagnostics, strict parity reporting, preview-first repair actions, and
  timestamped database backups before write operations.
• Local BPM, key, waveform, and artwork analysis for export preparation.
• Release packaging workflow for Tauri desktop builds.
