feat(qa-evidence): captures list the caller's declared-but-unrun required probes

GSTACK_QA_REQUIRED_PROBES (a JSON array of native child commands) makes every
capture print requiredRemaining; it never judges pass or fail. The functional
eval passes the webhook list from QA_WEBHOOK_REQUIRED_SCENARIOS, which the
verdict now reads too, so the nudge and the verdict share one source (agreed
with #3002's owner). CI webhook-report kept stopping with scenarios unrun.
