Deploys kube-vip as a DaemonSet on all k3s server nodes, advertising a VIP (192.168.20.2) via ARP. Eliminates the single-point-of-failure k3s-loadbalancer VM. - New kube_vip role: RBAC + DaemonSet templates, TLS SAN cert rotation - playbooks/kube-vip.yaml: migration playbook (serial=1, idempotent) - Updated k3s install tasks (server primary/secondary, agent) to use k3s_vip instead of the loadbalancer VM IP - Added k3s_vip: 192.168.20.2 to group_vars (below DHCP range .11-.250) Migration steps in playbook header comment.
