Adds terraform/edge, a root module with two providers: - Cloudflare 5.28.1: CNAMEs to the existing tunnel, plus an opt-in resource that can take the tunnel ingress list over when manage_tunnel_config is true. It is off by default because that resource REPLACES the whole list, and the tunnel is remotely managed from the dashboard today. - Tencent Cloud 1.83.38: VPC, subnet, security group with three rules, key pair, one CVM relay with cloud-init (WireGuard listener, forwarding sysctls, Caddy), and DNSPod A records for the .cn hostnames. The design keeps the homelab inbound-free: the relay terminates TLS in China and forwards over a WireGuard tunnel the cluster dials outbound. Cloudflare keeps serving every existing hostname untouched. Verified: terraform init succeeds for both providers, fmt clean, validate reports 0 errors, and plan resolves to 10 creates with placeholder variables. Provider-side name validation caught a real bug during that run: key pair and security group names allow only letters, digits and underscore, so the derived names use underscores. Not applied. Credentials come from CLOUDFLARE_API_TOKEN, TENCENTCLOUD_SECRET_ID and TENCENTCLOUD_SECRET_KEY; the WireGuard private key is TF_VAR only. State is local and git-ignored like terraform/zitadel. Blocked on facts this module cannot invent: the real .cn domain, whether it has an ICP filing, the CVM image ID, the operator CIDR, and the homelab WireGuard public key.
