[appimage] Phase 5: Ollama-Integration + Offline-Queue

Lokales Haiku-Equivalent: Bridge erkennt Ollama automatisch beim Start,
local-query Command für einfache Tasks (Commit-Messages, Übersetzungen).
Konfigurierbar über set-ollama-config.

Offline-Queue: Nachrichten werden bei fehlender Verbindung in SQLite
gequeuet und bei Reconnect automatisch gesendet. Commands:
queue_message, list_queued_messages, flush_offline_queue, clear_offline_queue.

 - **Weibliche TTS-Stimme**: Kerstin als Standard-Stimme, 5 deutsche Stimmen wählbar (`voice.rs`)
 - **MCP-Hub nativ (Phase 4)**: MCP-Server werden aus `~/.claude.json` geladen und beim Bridge-Start injiziert — kein CLI-Umweg nötig (`claude.rs`, `claude-bridge.js`)
 - **MCP-Verwaltung**: Tauri-Commands `list_mcp_servers`, `add_mcp_server`, `remove_mcp_server` — Server zur Laufzeit hinzufügen/entfernen
+- **Ollama-Integration (Phase 5)**: Lokales Modell für einfache Tasks — Auto-Detect, `local-query` Command, konfigurierbar (`claude-bridge.js`, `claude.rs`)
+- **Offline-Queue (Phase 5)**: Nachrichten bei fehlender Verbindung in SQLite queuen, später automatisch senden (`session.rs`)
 - **UTF-8 Crash Fix**: Kein Panic mehr bei Multi-Byte-Zeichen in DB-Abfragen (`db.rs`, `knowledge.rs`)
 - **Guard-Rails UI (Live)**: 3-Tab-Ansicht (Live-Feed/Regeln/Blockiert), Risiko-Statistik-Leiste, Ein-Klick-Freigabe bei Bestätigungsbedarf, guard-check Events vom Backend (`GuardRailsPanel.svelte`, `guard.rs`)
 - **D-Bus Desktop-Aktionen**: 10 vordefinierte Aktionen (Dolphin, Kate, Konsole, Firefox, Notify, Lock Screen), Aktionen-Grid im ProgramsPanel, CLI/GUI-Unterscheidung (`programs.rs`, `ProgramsPanel.svelte`)
