An ask_operator question that names a host or URL not among the task's
goal targets is tagged "contains target-derived text": the hosts go into
the transcript activity's Detail payload as target_derived_hosts, and the
transcript shows the tag on the request card when the field is set.
Hosts are read with intercept.ExtractTargets (the target gate's
command-string rules) from both the question and the task goal, and
compared without the port. The text the model reads, the pause, and the
operator's decision are unchanged: the tag is a visible hint only.
