Two lower-layer→feature inversions removed:
- Detail-route predicates (isAlbumDetailPath/isArtistDetailPath/isComposerDetailPath)
were defined in features/album's browse store but are pure URL checks. Extracted
to lib/navigation/detailRoutePaths; the browse store re-exports them so the
@/features/album barrel surface is unchanged. This frees albumDetailNavigation of
its only @/features import, so it moves utils/navigation → lib/navigation (drains
utils/navigation). Also fixes the M5 isArtistDetailPath misplacement.
- mixRatingFilter's sole feature dep is playback's userRatingOverrides and its only
binding consumer is playback's buildInfiniteQueueCandidates, so it belongs in the
playback feature: utils/mix → features/playback/utils (drains utils/mix). The
earlier handoff note that lib/api/subsonicStarRating consumes it was stale — that
is only a code comment, verified no runtime import.
Pure moves; tests pass unmodified. The share cluster + switchActiveServer stay in
utils/ — they are imported by the a11y-HELD PasteClipboardHandler, so relocating
them would rewrite a do-not-touch file.
