release: bump version to 0.0.4.3

Safe-Variante (Default):
  docker builder prune -a -f && docker image prune -a -f
  → Build-Cache + ungenutzte Images, KEINE Volumes angefasst.
  → 90% des Platzproblems geloest, Null Datenverlust-Risiko.

Aggressive Variante (nur auf Wunsch, hinter 'Mehr'-Button):
  docker system prune -a --volumes -f
  → Zusaetzlich ungenutzte Volumes.
  → Nur sicher wenn alle ARIA-Container LAUFEN (sonst werden
     openclaw-config/claude-config/aria-shared als "ungenutzt"
     behandelt und zerstoert — Sessions weg).
  → Hinweistext orange hervorgehoben mit Warnung.

Banner-Button 'Sicher aufraeumen' kopiert die sichere Variante.
'Mehr' klappt die Erklaerung der aggressiven Variante aus.

 ## Offen
 
 ### Bugs (Prioritaet)
-- [ ] Session-Persistenz: Bei Container-Restart wird immer aria-bridge geladen statt die zuletzt gewaehlte Session. Wird nicht persistent gespeichert.
-- [ ] App: Textnachrichten, Bilder und Anhaenge werden von ARIA nicht beantwortet — nur Sprachnachrichten funktionieren.
 - [ ] App: Audioausgabe hoert ab und zu einfach auf (mitten im Satz oder zwischen Chunks)
-- [ ] Auto-Update: APK-Installation schlaegt fehl (file:// URI exposed beyond app — braucht FileProvider fuer content:// URI)
-- [ ] Auto-Update: "Auf Updates pruefen" Button in App-Einstellungen
-- [ ] App: Kein Auto-Scroll zur letzten Nachricht beim App-Start (soll direkt springen, nicht animiert scrollen)
-- [ ] App: Bei neuen Nachrichten soll automatisch zur letzten Nachricht gescrollt werden
+- [ ] NO_REPLY wird als "NO" im Chat angezeigt — sollte still verworfen werden (Token nicht gesaeubert)
 
 ### App Features
-- [ ] App: Zu Anhaengen noch Text/Sprache hinzufuegen koennen (z.B. Bild senden + "Was siehst du?")
-- [ ] Wake Word on-device (Porcupine "ARIA" Keyword, Phase 2)
+- [ ] Wake Word on-device (Porcupine "ARIA" Keyword, Phase 2 — passives Lauschen)
 - [ ] Chat-History zuverlaessiger laden (AsyncStorage Race Condition)
 - [ ] Background Audio Service (TTS auch bei minimierter App)
+- [ ] Audio-Ducking: andere App-Audio-Ausgaben leiser stellen waehrend ARIA spricht (AudioFocus API)
+- [ ] Audio-Muten waehrend Aufnahme/Ohr-Modus: andere Audio stumm (wie WhatsApp-Sprachaufnahme)
+- [ ] Spracheingabe-Timeout erhoehen fuer laengere Texte
+- [ ] Generierte TTS-Audiodaten in der Chat-Nachricht einbetten (oder lokal cachen), Play-Button spielt aus Cache statt Regenerierung via XTTS. Base64 im Tag <soundfile></soundfile> (invisible) oder lokaler Datei-Cache mit Referenz in der Message.
+- [ ] QR-Code Onboarding: Diagnostic generiert QR mit RVS-Credentials, App scannt — keine manuelle Eingabe mehr
 
 ### TTS / Audio
-- [ ] XTTS Audio-Streaming verbessern (minimales Stottern bei Chunk-Uebergaengen)
 - [ ] Audio-Normalisierung (Lautstaerke zwischen Chunks angleichen)
-- [ ] Piper Voices Download ueber Diagnostic (neue Sprachen/Stimmen)
 
 ### Architektur
 - [ ] Bilder: Claude Vision direkt nutzen (aktuell nur Dateipfad an ARIA)
 - [ ] Auto-Compacting und Memory/Brain Verwaltung (SQLite?)
 - [ ] Diagnostic: System-Info Tab (Container-Status, Disk, RAM, CPU)
-- [ ] RVS Zombie-Connections endgueltig loesen (WebRTC statt WebSocket?)
+- [ ] RVS Zombie-Connections endgueltig loesen
+- [ ] Alle .env-Variablen ueber Diagnostic konfigurierbar machen (kein File-Sync mehr noetig, da alle ARIA-Container auf der gleichen VM laufen). Fallback .env bleibt fuer initialen Bootstrap.
+- [ ] XTTS-Container: kleine Web-Oberflaeche fuer Credentials/Server-Config, oder zentral aus Diagnostic per RVS push
+- [ ] Root-Cause OpenClaw Session-Reset: Herausfinden warum Sessions beim ersten chat.send nach Container-Restart verworfen werden (abortedLastRun / systemSent Theorie pruefen, ggf. Flag preemptiv patchen)
