notplantsandClaude Fable 5.1 31af820079 nix: one Hetzner host for the CI server + the orchestrator (#cc-ci)

The orchestrator's flake now builds the machine it shares with the cc-ci CI
server: `nixosConfigurations.cc-ci` composes cc-ci's nixosModules.cc-ci-server
(new flake input, nixpkgs + sops-nix follow ours), this repo's orchestrator
module (nix/modules/cc-ci.nix, exported as cc-ci-orchestrator, `cc-ci` kept
as an alias for notplants-nix) and the new nix/modules/orchestrator-host.nix
— the host contract those units always assumed (loops user, claude/opencode
CLIs, opencode web server + tailnet-only UI on 8443 since traefik owns
80/443, nix-ld, tool set, `ssh cc-ci` → loopback).

nix/hosts/cc-ci/{hardware,networking}.nix are PROVISIONAL copies of the old
server's layout so the flake evaluates; they get replaced by the
nixos-infect output of 195.201.88.249.

README.md is the deploy guide (Hetzner Debian → nixos-infect → this flake →
staging → data restore → cutover). archive/ holds the retired Incus/Hetzner
orchestrator host configs, the old terraform and the migration plans;
references updated. cc-ci-plan/plan-cc-ci-combined-host.md is the working
plan for the move.

The cc-ci orchestrator runs on a Hetzner cpx22; key host facts + the git-identity gotcha

node_type	type	originSessionId
memory	project	cd772f12-1978-47c3-894b-0ebbe0d2987f

The cc-ci orchestrator (loops + watchdog + this session) runs on a Hetzner cpx22 as of 2026-05-31, replacing the Incus VM (100.116.55.106).

Since 2026-09-07: ONE Hetzner host for CI server + orchestrator, public 195.201.88.249, tailnet cc-ci, flake host .#cc-ci (this repo). Before: orchestrator on Hetzner 134487234 (168.119.126.100 / 100.84.190.30, cc-ci-orchestrator-hetzner), shared with notplants.
Rebuild: sudo nixos-rebuild switch --flake .#cc-ci from /srv/cc-ci-orch (/srv/cc-ci is a symlink to it). The Bash tool runs as user loops (uid 1000, passwordless sudo) — plain nixos-rebuild switch fails on the profile symlink; use sudo.
Reboot-resilience: cc-ci-loops.service is enabled (wantedBy multi-user.target); ExecStartPre reboot-log.sh auto-logs reboots to REBOOTS.md. Its script runs launch.sh start, which stops+restarts the loops — so any rebuild that (re)starts the unit bounces the loops (they re-orient from git; harmless but noticeable).
Git-identity gotcha: the box had no git user.name/email configured; commits fail with "Author identity unknown". Set per-repo to match prior commits: autonomic-bot <autonomic-bot@git.autonomic.zone>.
