Track MediaItems set neither isPlayable nor isBrowsable, which Media3 turns into Auto's item flags, so every song in an album/playlist/ download/search list reached the car as an inert row. Both are now set, along with duration and track number. Artwork used the in-app http://localhost placeholder URL, which only the app's signed OkHttpClient can resolve. Auto and System UI fetch artwork themselves from their own processes, so it never loaded (logcat: "Invalid album art uri"). Adds CoverArtProvider, an exported content:// provider that fetches art through the signed client and caches it, and uses that URI on all MediaItems. The session's bitmap loader now goes through the same DefaultDataSource + OkHttp factory as playback. Coil in the phone UI reads the same content:// URI. BrowseTree: - Tapping one track in the car now queues the whole album/playlist/ downloads/search list from that track (onSetMediaItems), keyed by browser package so the phone's own queues are untouched. - Artists/albums/playlists lay out as a cover grid. - Honours page/pageSize; fixes an Int overflow in the paging helper. - Failures return LibraryResult errors instead of failed futures, and cancelled requests cancel their work. - The logged-out placeholder is no longer a browsable empty folder. Tests: unit tests for paging and cover-art id validation, plus an instrumented test that drives the service as an external MediaBrowser (skips itself when logged out). Verified on an emulator against a live server: playback, system media card and Now Playing artwork, no crashes. Not verified over a real Android Auto / Desktop Head Unit connection.
