v2.3.0

Added

• CLI now reports wall-clock duration for each command:
  • migrate: Done. Eligible files/folders moved: X; skipped: Y. Took Z.ZZs.
  • season-renamer: Done. Season folders renamed: N. Took Z.ZZs.
  • episode-renamer: Done. Episode files renamed: N. Took Z.ZZs.

Changed

• Migrate performance improvements and tuning:
  • Optional concurrency for metadata reads via --threads <N> (I/O bound).
  • --no-resolution to skip resolution comparisons when you want size-only heuristics.
  • Avoid resolution probing when the counterpart in library-b is missing (saves ffprobe/mediainfo calls).
• README updated to document timing output and new migrate flags.
