MC-Seite: services/agent.py + routers/agent.py (GET /api/agent/status:
Gateway/WebUI-Reachability + Verdrahtungs-Hinweise), AgentView (Status-
Tiles, Hermes-oeffnen-Button, Offline-Hinweis). deploy/hermes-webui.service

installieren, Brain=model:auto via Gateway, Tools/MCP verdrahten inkl.

Lokal verifiziert: agent/status + Frontend-Build + Browser (Hermes-View).
