Feat: Engine-Update-Mechanismus + Update-Checks (Hermes Agent/AnythingLLM) + WebUI->AnythingLLM

- Engine-Update: deploy/update-engine.sh laedt neuesten ggml-org Vulkan-Build + restart;
  MC_ENGINE_UPDATE_CMD verdrahtet, engine_update_job nutzt es (Script macht Restart selbst).
- Update-Checks: Hermes Agent (NousResearch/hermes-agent, Release-Datum vs. installiertes Commit)
  + AnythingLLM (Mintplex-Labs/anything-llm, neueste Version + /api/ping-Health), 1h-Cache.
  Neues Feld /api/maintenance/updates.components; UpdatesCard zeigt beide Zeilen.
- WebUI -> AnythingLLM: agent_status.webui_* zeigt jetzt auf ANYTHINGLLM_URL (192.168.178.155:3001,
  /api/ping); alle "Hermes WebUI"-Buttons/Labels (AgentView, AgentStatusCard, nav, GuideView,
  Services-Liste) -> "AnythingLLM". Lokaler hermes-webui-Dienst bleibt als Service-Control im SystemDrawer.
