Backend: FastAPI mit /api/health + /api/models (read-only aus llama-swap
config, Logik aus v1 portiert). Frontend: Vite + React + Tailwind v4 +
shadcn-Style App-Shell mit Cmd+K, Dark-default, PWA-Manifest; Modelle-View
live aus /api/models. Deploy-Geruest (systemd-Unit :9001, build/deploy-
Skripte, NOPASSWD-sudoers, kein Klartext-Passwort).

Verifiziert: Backend-Endpunkte + Frontend-Build + gerenderte Shell.
