# Instant auto-update: poll the registry and redeploy a container as soon as
# its published image differs from what is running. Cron runs this every 2 min
# (/boot/config/plugins/dynamix/registry-autoupdate.cron).
# Skips entirely while a CI job container is active: recreating gitgudlab would
# kill the registry mid-push, and the runner must not recreate itself mid-job
# (redeploy-gitgudlab-runner.sh also guards this itself).
