* feat(library): local lossless index, filters, and conserve dedicated page
Add SQLite-backed lossless album browse and advanced-search filtering,
wire All Albums and artist/album lossless drill-down mode, and hide the
standalone /lossless-albums nav entry from sidebar visibility settings
(conserved route, default off).
* docs(release): note lossless local index in CHANGELOG and credits (PR #871)
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.
