The runner group was limited to private repositories, so jobs from
public repositories never got a runner: Coolify still started a runner
for each matching job, which then waited idle until its timeout.
The runner group now allows every repository of the organization,
public ones too; existing private groups are updated. GitHub gives a
runner any queued job with matching labels, so pull request jobs are
refused inside the runner: a job-started hook fails jobs from
pull_request, pull_request_target and review events before any step
runs, and fails closed when the event is unknown. A new runner setting,
off by default, allows pull request jobs; the settings page then warns
to require approval for fork pull request workflows on GitHub.
