- Disable kubeControllerManager, kubeScheduler, kubeProxy ServiceMonitors
  in kube-prometheus-stack — Talos binds these to localhost (unscrappable)
  and uses Cilium instead of kube-proxy, eliminating false critical alerts
- Bump ArgoCD application-controller memory limit 1Gi → 2Gi to prevent
  OOMKills under load (125 restarts observed)
- Set Longhorn defaultReplicaCount to 2 (matches 2-node storage topology)
  and bump concurrent rebuild limit 2 → 5
