feat(2.0): Phase 4 — Hermes-Schicht (MC-Seite + Runbook)

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
(systemd-USER, :8787). Box-Runbook docs/HERMES_SETUP.md (hermes-webui
installieren, Brain=model:auto via Gateway, Tools/MCP verdrahten inkl.
mcp_mc+mcp_memory, SSH-Windows, LiteLLM-Caveat #26489).

Lokal verifiziert: agent/status + Frontend-Build + Browser (Hermes-View).
Box-Ausfuehrung der Verdrahtung steht aus (Runbook). Docs aktualisiert.
