tyrolize 1f9c2669a2 sops-nix bootstrap + Forgejo at git.tyrolize.ch
sops:
- devShell provides ssh-to-age and sets SOPS_AGE_KEY_FILE to
  $REPO/.sops-age-key.txt (gitignored, generated locally).
- .sops.yaml lists laptop + watcher recipients. The watcher recipient is
  derived from /etc/ssh/ssh_host_ed25519_key.pub via ssh-to-age, so the
  watcher decrypts using its SSH host key as the age identity at boot.
- hosts/watcher/secrets.yaml holds an `example` placeholder; sops-install-
  secrets surfaces it at /run/secrets/example (root-only).

Forgejo:
- modules/forgejo.nix enables services.forgejo (sqlite + daily tar.gz
  dump), built-in SSH server on :2222, HTTP on 127.0.0.1:3000.
- modules/website.nix adds the git.tyrolize.ch vhost reverse-proxying to
  localhost. Caddy gets a Let's Encrypt cert automatically.
- terraform/infomaniak/watcher.tf opens :2222 v4+v6 in the security group.
- Admin user `tyro` (role admin) created out-of-band via the gitea CLI.

Both services live on the watcher.

# sops-nix encryption rules.
#
# Recipients:
# - laptop: the age key in $REPO/.sops-age-key.txt (gitignored).
# To recover: keep a copy of that file in your password manager.
# - watcher: derived from the watcher's SSH host key
# (/etc/ssh/ssh_host_ed25519_key). If the watcher is rebuilt without
# restoring that host key, regenerate the recipient with:
# ssh tyro@<watcher> cat /etc/ssh/ssh_host_ed25519_key.pub | ssh-to-age
# and update this file accordingly.
#
# To edit an encrypted file: `sops hosts/watcher/secrets.yaml`
# To re-encrypt all files for new/changed keys: `sops updatekeys hosts/watcher/secrets.yaml`
