feat(2.0): Phase 2 — System/OS + Connect

System: services/system.py (psutil CPU/RAM/Disk, sysfs GPU/Temp guarded),
routers/system.py GET status + restart (Whitelist) + self-update (systemd-
USER, sudo-frei). Connect: services/connect.py (Cline/OpenCode/Zed/Continue/
Claude Code/Memory-MCP → Gateway model:auto, LAN-IP-Override), routers/
connect.py. Frontend: SystemView (Metrik-Bars) + ConnectView (Tool-Tabs,
Copy, IP-Override).

Lokal verifiziert: Backend-Smoke + Frontend-Build + Browser (System-Bars,
Connect-Snippets). Docs aktualisiert (README/STATUS/Plan).
