- Add modules/nixos/gitea-runner.nix: NixOS module for act_runner in
shell mode, with options for enable, instanceURL, name, labels, and
tokenFile (agenix secret path).
- Deploy gitea-runner to jeremiah, isaiah, zeke, and linode with
appropriate labels. Agenix secret placeholders left with TODOs.
- Add .gitea/workflows/update-flake-lock.yaml: weekly workflow (Sunday
midnight) that runs nix flake update and opens a PR if flake.lock
changed, using GITEA_TOKEN secret for authentication.
Closes part of #15 (NixOS shell runners + flake-lock workflow).
- manifests/gitea/dump-cronjob.yaml: Remove --skip-log, --skip-custom-dir,
--skip-db flags to make backup complete
- manifests/gitea/dump-cronjob.yaml: Replace NFS volume + cleanup container
with S3 upload to backup-gitea bucket using MinIO client (mc).
30-day lifecycle set via mc ilm. Uses minio_key/minio_secret from
existing gitea-config secret.
- hosts/unstable/hosea/default.nix: Replace raw services.restic.backups.albyhub
block with greg.backup.jobs.albyhub using the greg.backup module.
Remove manual age.secrets.restic-env and age.secrets.restic-pw entries
since the greg.backup module declares them.
