* fix(ui): split OpenSubsonic album and track artists in header and player
Album detail header uses albumArtists from album or child songs; player bar,
mobile player, and mini player use structured track artists with per-id links.
Adds deriveAlbumHeaderArtistRefs helper and OpenArtistRefInline.
Fixes#552
* docs: changelog and credits for OpenSubsonic artist links (PR #696)
111 of 122 top-level src/utils/ files move into 16 topic folders (audio,
cache, cover, share, server, playback, playlist, deviceSync, waveform,
mix, format, export, changelog, ui, perf, componentHelpers). True
singletons with no cluster stay at the utils/ root.
Pure file-move: a path-aware codemod rewrote 539 relative-import
specifiers across 275 files; no logic touched. The hot-path coverage
gate list (.github/frontend-hot-path-files.txt) is updated to the new
paths for the 11 gated utils files — a mechanical consequence of the
move, not a CI change. tsc is green.
