Implement HA control plane with Load Balancer (3-3 topology) Major changes: - Terraform: Scale to 3 control planes (cx23) + 3 workers (cx33) - Terraform: Add Hetzner Load Balancer (lb11) for Kubernetes API - Terraform: Add kube_api_lb_ip output - Ansible: Add community.network collection to requirements - Ansible: Update inventory to include LB endpoint - Ansible: Configure secondary CPs and workers to join via LB - Ansible: Add k3s_join_endpoint variable for HA joins - Workflow: Add imports for cp-2, cp-3, and worker-3 - Docs: Update STABLE_BASELINE.md with HA topology and phase gates Topology: - 3 control planes (cx23 - 2 vCPU, 8GB RAM each) - 3 workers (cx33 - 4 vCPU, 16GB RAM each) - 1 Load Balancer (lb11) routing to all 3 control planes on port 6443 - Workers and secondary CPs join via LB endpoint for HA Cost impact: +~€26/month (2 extra CPs + 1 extra worker + LB) 2026-03-23 02:39:39 +00:00			`kube_api_endpoint={{ kube_api_lb_ip }}`
