release: bump version to 0.0.5.1

XTTS-Bridge:
  - empfaengt neuen voice_preload Type, rendert stumm "ja." fuer die Stimme
    via TTS-Queue (damit kein Konflikt mit echtem TTS)
  - horcht zusaetzlich auf config-Broadcasts: wenn Diagnostic global die
    Stimme wechselt, wird auto-preloaded
  - broadcastet voice_ready mit Dauer (loadMs) oder error

RVS: voice_preload + voice_ready zur ALLOWED_TYPES-Liste.

App (SettingsScreen): beim Wechsel senden wir voice_preload, zeigen einen
Spinner in der Voice-Row und einen Toast mit "Stimme X bereit (Ns)".
App (ChatScreen): Toast auch hier — falls User gerade nicht in Settings ist.

Diagnostic (server+UI): voice_ready wird an Browser durchgereicht, ein
Status-Text unter dem Voice-Dropdown zeigt "wird geladen" → "bereit".

+
+ARIA-VM
+└── aria-bridge: tts_engine="xtts" → xtts_request via RVS → wartet auf xtts_response
+```
+
+### Voraussetzungen
+
+- Docker Desktop mit WSL2 (Windows) oder Docker mit NVIDIA Runtime (Linux)
+- NVIDIA Container Toolkit
+- GPU mit mindestens 4GB VRAM (6GB+ empfohlen)
+- **Gleicher RVS_TOKEN wie auf der ARIA-VM!**
+
+### Setup
+
+```bash
+cd xtts
+cp .env.example .env
+# .env mit RVS-Verbindungsdaten fuellen (gleicher Token wie ARIA-VM!)
+docker compose up -d
+# Erster Start laedt ~2GB Model herunter (danach gecacht)
+```
+
+**Wichtig:** Der XTTS-Server laeuft intern auf Port **8020** (nicht 8000).
+Das Model wird im Volume `xtts-models` gecacht und muss nur einmal geladen werden.
+
+### Features
+
+- **Natuerliche Stimmen**: Deutlich bessere Qualitaet als TTS der alten Generation
+- **Voice Cloning**: Eigene Stimme mit 6-10s Audio-Sample (~2s Latenz auf RTX 3060)
+- **Streaming**: PCM-Chunks alle ~170ms → App spielt ohne Warten nahtlos
+- **16 Sprachen**: Deutsch, Englisch, Franzoesisch, etc.
+
+### TTS-Config
+
+In der Diagnostic unter Einstellungen → Sprachausgabe:
+- **TTS aktiv**: Global An/Aus
+- **XTTS Stimme**: Default oder gecloned (Maia, etc.)
+
+> XTTS ist die einzige Engine — wenn der Gaming-PC offline ist, bleibt ARIA stumm.
+> Chat-Antworten kommen weiter an (nur kein Audio).
+
+### Stimme klonen
+
+1. "Stimme klonen" → Audio-Dateien hochladen (WAV/MP3, 1-10 Dateien, min. 6-10s gesamt)
+2. Name vergeben → "Stimme erstellen"
+3. "Laden" klicken → neue Stimme in der Auswahl
+4. Stimme auswaehlen → Config wird automatisch gespeichert
+
+> **Tipp:** Fuer beste Ergebnisse: saubere Aufnahme, eine Stimme, kein Hintergrund,
+> 10-30 Sekunden Gesamtlaenge. Mehrere kurze Dateien werden zusammengefuegt.

+# ARIA Issues & Features
+
+## Erledigt
+
+- [x] Bildupload funktioniert (Shared Volume /shared/uploads/)
+- [x] Sprachnachrichten werden als Text angezeigt (STT → Chat-Bubble)
+- [x] Cache leeren + Auto-Download von Anhaengen
+- [x] ARIA liest Nachrichten vor (TTS via Piper)
+- [x] Autoscroll zur letzten Nachricht (inverted FlatList)
+- [x] Bilder im Chat groesser + Vollbild-Vorschau
+- [x] Ohr-Button → Gespraechsmodus (Auto-Aufnahme nach ARIA-Antwort)
+- [x] Play-Button in ARIA-Nachrichten fuer Sprachwiedergabe
+- [x] Chat-Suche in der App (Lupe in Statusleiste)
+- [x] Watchdog mit Container-Restart (2min Warnung → 5min doctor --fix → 8min Restart)
+- [x] Abbrechen-Button im Diagnostic Chat
+- [x] Nachrichten Backup on-the-fly (/shared/config/chat_backup.jsonl)
+- [x] Grosse Nachrichten satzweise aufteilen fuer TTS
+- [x] RVS Nachrichten vom Smartphone gehen durch
+- [x] Stimmen-Einstellungen (Ramona/Thorsten, Speed pro Stimme)
+- [x] Highlight-Trigger konfigurierbar in Diagnostic
+- [x] XTTS v2 Integration (Gaming-PC, GPU, Voice Cloning)
+- [x] XTTS Voice Cloning (Audio-Samples hochladen, eigene Stimme)
+- [x] TTS Engine waehlbar (Piper/XTTS) in Diagnostic + App
+- [x] Auto-Update System (APK via RVS WebSocket)
+- [x] Auto-Update: APK-Installation via FileProvider
+- [x] Auto-Update: "Auf Updates pruefen" Button in App-Einstellungen
+- [x] Audio-Queue (sequentielle Wiedergabe, kein Ueberlappen)
+- [x] Textnachrichten werden von ARIA beantwortet (Bridge chat handler fix)
+- [x] Mehrere Anhaenge + Text vor dem Senden (Pending-Vorschau)
+- [x] Paste-Support fuer Bilder in Diagnostic Chat
+- [x] Markdown-Bereinigung fuer TTS (fett, kursiv, code, links, etc.)
+- [x] SSH Volume read-write fuer Proxy (kein -F Workaround mehr)
+- [x] Diagnostic: Sessions als Markdown exportieren (Download-Button)
+- [x] Speech Gate: Aufnahme wird verworfen wenn keine Sprache erkannt (verhindert dass Umgebungsgeraeusche an Whisper gehen)
+- [x] Session-Persistenz: Gewaehlte Session bleibt ueber Container-Restarts erhalten (sessionFromFile-Flag, atomic write)
+- [x] Diagnostic: "ARIA denkt..." bleibt nicht mehr stehen (pipelineEnd broadcastet immer idle, auch bei Timeout/Fehler/Disconnect)
+- [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] Streaming TTS (Weg A): XTTS → PCM-Stream → aria-bridge → App AudioTrack MODE_STREAM, keine WAV-Gaps mehr
+- [x] Piper komplett entfernt: nur noch XTTS v2 als TTS-Engine (remote, GPU auf Gaming-PC). Wenn XTTS offline ist, ist ARIA stumm — bewusst akzeptiert.
+- [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
+- [ ] Audio-Normalisierung (Lautstaerke zwischen Chunks angleichen)
+
+### 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)
