v1.14.0

Additive (MINOR) release: optional recording-identity keys, so a pack can carry a stable,
open, exact identity for the recording it transcribes.

Added

• New optional top-level manifest keys mbid — the
  MusicBrainz Recording MBID of the recording the pack transcribes (lowercase canonical
  UUID) — and isrc — its International Standard
  Recording Code. Both are author-set exact identity keys: a consumer SHOULD prefer them over
  free-text artist/title matching when grouping charts of the same recording or looking up
  external metadata, and SHOULD trust mbid when the two disagree. The stored ISRC is the bare
  12-character code — the hyphens in the common display form are presentation only, stripped
  when writing and before comparing.
  schemas/manifest.schema.json validates both formats.

Compatibility

• Purely additive. Older Readers ignore both keys and still load. Nothing is removed, renamed,
  or repurposed.
