archive: repo moved to titaniumtown/nixos

Additive. The new unified nixos repo (projects/nixos/) uses a fresh git-crypt
key so we can retire the two per-repo keys later. Deploying this change alone
makes /run/agenix/git-crypt-key-nixos available on muffin; the nixos CI's
git-crypt unlock step can then succeed once the new repo lands on Gitea.

+# server-config (archived)
+
+This repository has been unified with its sibling `dotfiles` into
+[**titaniumtown/nixos**](https://git.sigkill.computer/titaniumtown/nixos).
+
+The final pre-unification commit is tagged `final-before-unify`.
+
+See the new repo's `README.md` and `AGENTS.md` for:
+
+- current flake layout (hosts: mreow, yarn, muffin)
+- deploy workflow
+- git-crypt / agenix setup
+
+Do **not** push new commits here — CI has been disabled, and muffin's harmonia
+binary-cache no longer serves paths from `/var/lib/dotfiles-deploy/`.
