release: bump version to 0.0.3.8

feat: Whisper model selector + 16kHz mono recording
- App: AudioSamplingRateAndroid 16000 + AudioChannelsAndroid 1 → Whisper bekommt direkt sein Ziel-Format, kein Resample mehr - Bridge: STTEngine.reload() laedt Modell zur Laufzeit neu (tiny/base/small/medium/large-v3) - Bridge: Config-Message triggert Hot-Reload wenn whisperModel sich aendert - Bridge: Default auf 'medium' (besser als 'small' bei aehnlicher Latenz) - Diagnostic: Neue Sektion "Whisper (Spracherkennung)" mit Dropdown, auto-save bei Auswahl, beim Laden wird der gespeicherte Wert gesetzt - Diagnostic/Server: send_voice_config merged whisperModel in voice_config.json - aria.env.example: WHISPER_MODEL + WHISPER_LANGUAGE dokumentiert Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

+## XTTS v2 — GPU TTS Server (optional)
+
+Laeuft auf einem separaten Rechner mit NVIDIA GPU (z.B. Gaming-PC mit RTX 3060).
+Verbindet sich ueber RVS mit der ARIA-Infrastruktur — kein VPN noetig, funktioniert
+ueber verschiedene Netze hinweg.
+
+### Architektur
+
+```
+Gaming-PC (Windows, RTX 3060, Docker Desktop + WSL2)
+├── aria-xtts        XTTS v2 GPU Server (Port 8020 intern)
+└── aria-xtts-bridge RVS-Relay (empfaengt Requests, sendet Audio)
+    └── Beide teilen ./voices/ Volume fuer Voice Cloning
+
+         ↕ RVS (Rechenzentrum, WebSocket Relay)
+
+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 Piper
+- **Voice Cloning**: Eigene Stimme mit 6-10s Audio-Sample (~2s Latenz auf RTX 3060)
+- **16 Sprachen**: Deutsch, Englisch, Franzoesisch, etc.
+- **Fallback**: Wenn XTTS nicht erreichbar, nutzt die Bridge automatisch Piper
+
+### TTS-Engine umschalten
+
+In der Diagnostic unter Einstellungen → Sprachausgabe:
+- **TTS aktiv**: Global An/Aus
+- **TTS Engine**: Piper (lokal, CPU, schnell) oder XTTS v2 (remote, GPU, natuerlich)
+- **Piper**: Standard-Stimme, Highlight-Stimme, Speed pro Stimme
+- **XTTS**: Stimmen-Auswahl, Voice Cloning
+
+### Stimme klonen
+
+1. TTS Engine auf "XTTS v2" stellen
+2. "Stimme klonen" → Audio-Dateien hochladen (WAV/MP3, 1-10 Dateien, min. 6-10s gesamt)
+3. Name vergeben → "Stimme erstellen"
+4. "Laden" klicken → neue Stimme in der Auswahl
+5. 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.

+- [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)
