- Toggle-Buttons in Navidrome-Tab: "📀 Alben" ↔ "🎤 Künstler"
- Artist-Liste zeigt Namen pro Künstler, Tap lädt alle Songs des Künstlers
- _playArtist() Methode lädt Künstler-Songs via getArtistSongs() API
- Albums/Artists sind Lazy-Loaded (nur beim Toggle laden)

- Neuer 4. Tab: '🌐 Server' zeigt Alben vom Musikserver
- Album-Liste laden und anzeigen (AsyncBuilder)
- Tap auf Album → alle Songs in Queue laden + abspielen
- Graceful Fallback wenn Server nicht verbunden
- Tests: 70/70 grün
- Analyzer: ✅ keine Fehler
Phase 1 P0-Feature: Album-Browser vom Server
- Library screen now has a TabBar (Alle / Künstler / Alben) inside a
DefaultTabController; scan/permission/error banners stay above the
TabBarView so they remain visible regardless of the active sub-tab
- New lib/library/song_grouping.dart: pure, unit-tested functions
groupByArtist/groupByAlbum (null artist/album -> "Unbekannt" /
"Unbekanntes Album", alphabetically sorted) plus albumArtistLabel
("Verschiedene Interpreten" when an album mixes artists)
- New lib/library/artist_list.dart + album_list.dart: StreamBuilder on
MeloDb.watchSongs(), grouped client-side, tapping a row pushes a
SongList screen for that artist/album; album rows show a CoverImage
thumbnail from the first song's coverPath
- Existing "Alle" tab content (recently-added strip, full song list,
empty state) preserved unchanged, moved into _AllSongsTab
Genre browsing is intentionally out of scope: the Songs table has no
genre column and neither scanner extracts genre metadata — needs a
schema migration + scanner work in a future task.

- "Zuletzt hinzugefügt" aus dem alten HomeScreen in die Bibliothek verschoben:
horizontal scrollende Leiste über der vollen Songliste, nur sichtbar wenn
nicht leer und nicht gerade gescannt wird
- home_screen.dart entfernt (Funktionalität jetzt Teil von LibraryScreen)
- HomeShell-Tabs auf die finale Struktur umgestellt: NowPlayingScreen an
Position 0, Playlisten- und Settings-Platzhalter an ihren finalen
Positionen (werden in späteren Tasks durch echte Screens ersetzt)
- BottomNavigationBar-Icons/Labels an die neue Reihenfolge angepasst
- MiniPlayer wird ausgeblendet, solange der Now-Playing-Tab aktiv ist
(redundant, da der Tab selbst schon die volle Wiedergabe-Ansicht zeigt)

## Critical Blockers Fixed
- Remove playbackState.addError() which broke audio_service permanently
- Move error handling from audio_handler to song_list where UI context exists
- Display error in SnackBar instead of destroying playback stream
- Add escapeChar parameter to LIKE queries for correct wildcard handling
- Fixes broken search for titles with _ or % characters
- Add dismissScanError() method to allow closing error banner
- Previously banner couldn't be dismissed (missing notifyListeners())
## Improvements
- Remove dead livePaths list, use companions.isNotEmpty instead
- Add initial progress update to show total files when scan starts
- Add tooltip to now_playing_screen Zurück button
- Add proper error handling in song_list with async/await
## Testing
- Add regression test for CRITICAL-1: empty scan doesn't delete songs
- Add regression test for CRITICAL-2: tombstoned files restore on re-scan
- All 11 tests pass

- HIGH-3: Add error handling for scan failures
- Wrap scanFolders/scanAndroidMediaStore in try/catch
- Display scanError banner in LibraryScreen
- HIGH-4: Add error handling for playback failures
- Wrap loadPlaylist in try/catch
## Medium Priority Fixes
- MEDIUM-1: Replace ! with ?? to handle unknown ProcessingState
- MEDIUM-2: Escape LIKE wildcards in search queries
- MEDIUM-4: Display StreamBuilder errors instead of treating as empty
- MEDIUM-8: Add tooltips to all IconButtons for accessibility
- Add doc comments to public database APIs
