feat(cluster): Rolling Update — Secondary-first upgrade orchestration (v1.2.3)
POST /cluster/rolling-update startet den gestaffelten Upgrade-Prozess: 1. Secondary via mTLS /agent/cluster/trigger-update anstoßen 2. /agent/cluster/version pollen bis Secondary Version-Flip zeigt (max 10 min) 3. Primary self-upgrade via systemd-run (identisch zu /system/upgrade) State wird in /var/lib/edgeguard/rolling-update-state.json persistiert: Phasen: updating-secondary → waiting-secondary → updating-primary. "done" wird nicht geschrieben — Prozess stirbt beim Upgrade. UI erkennt Abschluss via /system/health version-flip (analog Single-Node-Upgrade). UI: UpdateBanner erkennt Cluster-Modus (/cluster/status mode="cluster") und tauscht den "Install now"-Button gegen "Rolling Update (Cluster)" aus. Multi-Step-Modal zeigt die drei Phasen; ab updating-primary wechselt der Client auf /system/health polling. Aggregator.PostPeer: neuer einzel-POST-Helper für mTLS-trigger-update. WithVersion(): ClusterHandler bekommt Binary-Version für /agent/cluster/version. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
