The cc-ci server already runs on Hetzner (migration done; nix/hosts/cc-ci-hetzner
landed directly on main 2026-05-31). PR#2's host config was superseded by newer
main commits, but its terraform/ provisioning scaffolding (cpx32 + nixos-infect)
was never preserved. Add it here as the infrastructure-of-record so the box is
reproducible. .gitignore keeps tfstate + secret tfvars out; HCLOUD_TOKEN is an
env var at apply time (no secrets committed). PR#2 closed as superseded.
