terraform+nix: Hetzner orchestrator server (cpx11, nixos-infect, cc-ci-orchestrator-hetzner flake host)
Adds terraform/ to provision a Hetzner cpx11 (2 vCPU / 2 GB dedicated AMD / 40 GB NVMe) for the loops runtime, and a flake + NixOS host config to converge it — replacing the slow b1 Incus VM. Mirrors the cc-ci server terraform (same nixos-infect pin, same pattern). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
