* feat(artwork): add KindDiscArtwork and ParseDiscArtworkID
Add new disc artwork kind with 'dc' prefix for per-disc cover art
support. The composite ID format is albumID:discNumber, parsed by
the new ParseDiscArtworkID helper.
* feat(conf): add DiscArtPriority configuration option
Default: 'disc*.*, cd*.*, embedded'. Controls how per-disc cover
art is resolved, following the same pattern as CoverArtPriority
and ArtistArtPriority.
* feat(artwork): implement extractDiscNumber helper
Extracts disc number from filenames based on glob patterns by
parsing leading digits from the wildcard-matched portion.
Used for matching disc-specific artwork files like disc1.jpg.
* feat(artwork): implement fromDiscExternalFile source function
Disc-aware variant of fromExternalFile that filters image files
by disc number (extracted from filename) or folder association
(for multi-folder albums).
* feat(artwork): implement discArtworkReader
Resolves disc artwork using DiscArtPriority config patterns.
Supports glob patterns with disc number extraction, embedded
images from first track, and falls back to album cover art.
Handles both multi-folder and single-folder multi-disc albums.
* feat(artwork): register disc artwork reader in dispatcher
Add KindDiscArtwork case to getArtworkReader switch, routing
disc artwork requests to the new discArtworkReader.
* feat(subsonic): add CoverArt field to DiscTitle response
Implements OpenSubsonic PR #220: optional cover art ID in
DiscTitle responses for per-disc artwork support.
* feat(subsonic): populate CoverArt in DiscTitle responses
Each DiscTitle now includes a disc artwork ID (dc-albumID:discNum)
that clients can use with getCoverArt to retrieve per-disc artwork.
* style: fix file permission in test to satisfy gosec
* feat(ui): add disc cover art display and lightbox functionality

* refactor: simplify disc artwork code
- Add DiscArtworkID constructor to encapsulate the "albumID:discNumber"
format in one place
- Convert fromDiscExternalFile to a method on discArtworkReader,
reducing parameter count from 6 to 2
- Remove unused rootFolder field from discArtworkReader
* style: fix prettier formatting in subsonic index
* style(ui): move cursor style to makeStyles in SongDatagrid
* feat(artwork): add discsubtitle option to DiscArtPriority
Allow matching disc cover art by the disc's subtitle/name.
When the "discsubtitle" keyword is in the priority list, image files
whose stem matches the disc subtitle (case-insensitive) are used.
This is useful for box sets with named discs (e.g., "The Blue Disc.jpg").
* feat(configuration): update discartpriority to include cover art options
