terraform: IaC-of-record for the cc-ci Hetzner host (salvaged from PR#2)
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 PR#2's host config was superseded by newer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 PR#2 closed as superseded.

# Stage 1 — convert Debian 12 → NixOS via nixos-infect (pinned revision).
#
# nixos-infect generates /etc/nixos/{configuration.nix,hardware-configuration.nix,networking.nix}
# with Hetzner-correct bootloader (GRUB, not systemd-boot) and networking, then reboots into NixOS.
#
# After the reboot:
# - SSH as root is available (key registered with Hetzner survives infect)
# - Run Stage 2 per terraform/README.md: clone cc-ci + cc-ci-secrets, provision the bootstrap
# age key, then `nixos-rebuild switch --flake .#cc-ci-hetzner`
#
# Logs are written to /var/log/nixos-infect.log on the server for post-mortem inspection.
# The server reboots automatically at the end of infect — wait ~5 min before sshing in.
