- Server device exposing CPU/RAM/GPU/temperature/battery sensors via /api/v1/system/performance, plus last-restart timestamp (cached with jitter threshold so the recorder doesn't see poll wobble) and version. - Update entity backed by /api/v1/system/update — installs via /apply, hides the install button when the server reports can_auto_update=false. - Sync-clock entities: reset button, speed number, running switch, and the event listener now refreshes on entity_changed events too. - Bump manifest to 0.4.0.
