* Enhance CachedImage and ArtistDetail components with improved image caching and priority handling - Refactor CachedImage to utilize a priority system for image loading based on viewport visibility, improving performance during scrolling. - Update useCachedUrl to accept an optional getPriority function for better cache management. - Optimize ArtistDetail and Artists components by using useMemo for cover art URLs, reducing redundant calculations and improving rendering efficiency. - Adjust image loading logic in CachedImage to ensure smoother transitions and avoid unnecessary fetch requests. * perf(ui): unblock IDB cover art, stabilize mainstage rails and virtual lists Let IndexedDB reads bypass the network concurrency slot so cached thumbnails paint without queueing behind remote fetches; debounce disk eviction during heavy scrolling. Fix mainstage horizontal rails: dedupe album/song ids for React keys, widen artwork budget overscan, avoid resetting the budget on list append, and raise Home initial artwork budgets. CachedImage treats already-decoded images as loaded; rail cards load cover images eagerly. Refresh dynamic color extraction and extend virtual scrolling / scroll roots on Albums, Artists, Playlists, and related surfaces. Remove local agent-only commit instructions from the repository tree. * perf(virtual): viewport-based overscan for main scroll lists Drive TanStack Virtual overscan from measured scroll height so each list renders about one screen of extra rows above and below the viewport for snappier scrolling on Albums, Artists (list mode), and Tracks virtual song list. Introduce useResizeClientHeight helpers (ID + ref) for ResizeObserver-based clientHeight tracking. * docs(changelog): note PR #468 UI cover cache, rails, and virtual lists Add a coarse summary under 1.46.0 Changed for cover-art pipeline, mainstage rails, viewport-based overscan, and library/chrome polish.
