The dry-run publish checks split into nine scenarios, one per model
and refusal reason; the prompt text, refusal exit code (130) and
publication report are the observables. WithStdin joins the Action
modifiers to feed prompt answers. TestPublish stays legacy: it drives
a real registry container and loads oci:// projects with multiple -f
files. Only the oci/ fixture subtree it needs survives.
