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

 - [x] App: "ARIA denkt..." Indicator + Abbrechen-Button (Bridge spiegelt agent_activity via RVS)
 - [x] Whisper STT: Model-Auswahl in Diagnostic (tiny/base/small/medium/large-v3), Hot-Reload in Bridge, Default auf medium
 - [x] App: Audio-Aufnahme explizit 16kHz mono (spart Resample, optimal fuer Whisper)
+- [x] Gespraechsmodus: Speech-Gate strenger (-28dB / 500ms) — keine Umgebungsgeraeusche mehr
+- [x] Gespraechsmodus: Max-Dauer 30s pro Aufnahme, Cache-Cleanup alter Files, Messages-Array gekappt (500)
+- [x] Diagnostic: Archivierte Session-Versionen (.reset.*) werden angezeigt + exportierbar — OpenClaw resettet Sessions bei erster Nutzung nach Container-Restart, Inhalt ist aber in .reset.<timestamp> Dateien gesichert
+- [x] tools/export-jsonl-to-md.js: CLI-Konverter fuer beliebige Session-JSONL zu Markdown
+- [x] NO_REPLY-Filter in Bridge + Diagnostic — still verworfen (kein Chat, kein TTS)
+- [x] Audio-Ducking + Exklusiv-Focus (Kotlin AudioFocusModule): andere Apps leiser bei TTS, pausiert bei Aufnahme
+- [x] TTS-Cleanup serverseitig: Code-Bloecke raus, Einheiten ausgeschrieben (22GB → Gigabyte), Abkuerzungen buchstabiert (CPU), URLs zu "ein Link". `<voice></voice>` Tag wird bevorzugt wenn ARIA ihn liefert.
+- [x] QR-Code Onboarding: Diagnostic generiert QR, App scannt (bestehender QRScanner funktioniert out of the box)
+- [x] TTS-Audio-Cache im Filesystem: Piper-Audio wird mit messageId verknuepft, als WAV in DocumentDirectory/tts_cache gespeichert, Play-Button spielt aus Cache statt regenerieren
+- [x] Config via Diagnostic: RVS-Credentials + Aria-Auth-Token via /api/runtime-config, persistiert in /shared/config/runtime.json, Bridge liest beim Start (Overrides der ENV)
 
 ## Offen
 
 ### Bugs (Prioritaet)
 - [ ] App: Audioausgabe hoert ab und zu einfach auf (mitten im Satz oder zwischen Chunks)
+- [ ] NO_REPLY wird als "NO" im Chat angezeigt — sollte still verworfen werden (Token nicht gesaeubert)
 
 ### App Features
 - [ ] 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 (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
+- [ ] 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)
