test-build: add --pull to refresh a stale local image
require_image pulled only when the image was missing, so once the
image-builder rebuilt a registry tag the local copy went stale with no
warning. --pull runs `docker pull` first, which compares digests itself
and costs one manifest request when nothing changed. If the registry is
unreachable it falls back to the local copy with a warning, and still
fails when there is none.
The README documents a daily cron pull for machines that run test-build,
and the skill notes that local images are not refreshed automatically.
