### Added

- `ubuntu-latest-full` runner label — opt-in GitHub-parity image, pulls nothing until a job matches it (#144)

### Fixed

- CI's `check` job installs shellcheck where the runner image lacks it — rig's own CI passes on rig-installed Forgejo runners (#144)
- `forgejo-runner install` warns on a plain converge when a runner was registered with a retired default label set (#144)
