release: bump version to 0.0.4.1

Der QR wurde mit createImgTag() als fester Pixel-IMG gerendert und
ueberlappte den Warnhinweis + Button rechts daneben. Fix:

- createSvgTag mit cellSize=4 + scalable=true
- SVG skaliert auf width:100%/height:100% der 220x220 Box
- Container: flex-shrink:0 (damit Flex ihn nicht weiter schrumpft)
- overflow:hidden als Sicherheit

 ## 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: release.sh kopiert APK nicht auf den RVS-Server (rvs/updates/ bleibt leer)
+- [ ] NO_REPLY wird als "NO" im Chat angezeigt — sollte still verworfen werden (Token nicht gesaeubert)
-- [ ] 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
 
 ### 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 — passives Lauschen)
-- [ ] Wake Word on-device (Porcupine "ARIA" Keyword, Phase 2)
 - [ ] 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)
+- [ ] XTTS Audio-Streaming (PCM-Stream statt WAV-Dateien, eliminiert Stottern komplett)
 - [ ] Audio-Normalisierung (Lautstaerke zwischen Chunks angleichen)
 - [ ] Piper Voices Download ueber Diagnostic (neue Sprachen/Stimmen)
+- [ ] TTS-Text-Aufbereitung: Code-Bloecke rausfiltern, Einheiten ausschreiben ("22GB" → "zweiundzwanzig Gigabyte"). Zwei Varianten denkbar: (a) server-side Cleanup in Bridge, (b) ARIA schreibt `<voice></voice>` Block der in UI hidden bleibt aber fuer TTS genutzt wird.
+- [ ] Piper evtl. komplett entfernen (klingt schlecht vs. XTTS) — oder nur als Fallback wenn XTTS offline ist
 
 ### 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)
