feat: MCP-Server für remote_execute + Inline-Choice-UI

- Python MCP-Server (stdio, JSON-RPC 2.0) für remote_execute via Claude CLI
- Interner API-Endpoint /api/internal/remote-execute mit Token-Auth
- MCP-Config wird automatisch generiert wenn Remote-Verbindung vorhanden
- Auth-Middleware: /api/internal/ von Auth ausgenommen
- Frontend: :::ASK_USER_CHOICE::: Blöcke als interaktive Buttons rendern
- Streaming: Unvollständige Choice-Blöcke werden während des Streams versteckt
- tool-ui.js: MCP-Tool-Namen generisch normalisieren (mcp__server__tool → tool)
