Add IPv6 support for Typhoon Azure clusters * Define a dual-stack virtual network with both IPv4 and IPv6 private address space. Change `host_cidr` variable (string) to a `network_cidr` variable (object) with "ipv4" and "ipv6" fields that list CIDR strings. * Define dual-stack controller and worker subnets. Disable Azure default outbound access (a deprecated fallback mechanism) * Enable dual-stack load balancing to Kubernetes Ingress by adding a public IPv6 frontend IP and LB rule to the load balancer. * Enable worker outbound IPv6 connectivity through load balancer SNAT by adding an IPv6 frontend IP and outbound rule * Configure controller nodes with a public IPv6 address to provide direct outbound IPv6 connectivity * Add an IPv6 worker backend pool. Azure requires separate IPv4 and IPv6 backend pools, though the health probe can be shared * Extend network security group rules for IPv6 source/destinations Checklist: Access to controller and worker nodes via IPv6 addresses: * SSH access to controller nodes via public IPv6 address * SSH access to worker nodes via (private) IPv6 address (via controller) Outbound IPv6 connectivity from controller and worker nodes: ``` nc -6 -zv ipv6.google.com 80 Ncat: Version 7.94 ( https://nmap.org/ncat ) Ncat: Connected to [2607:f8b0:4001:c16::66]:80.
