chore: address Copilot review round 10

The CI half of the wiring vouch matched the workflow's raw text, so a YAML
comment, a step `name:`, or an unused anchor mentioning `npm run
verify:skills:cli` satisfied it — including this guard's own docblock wording.
Deleting the real step would then have left `verify:skills` green, which is the
vacuous-guard failure the vouch exists to prevent.

It now reads the workflow's executable regions via `extractExecutableRegions`,
the same helper the #2146 workflow gate is built on, and matches only a `run:`.
Covered by three should-not-count cases (comment, step name, workflow input)
plus a multi-line `run:` that must count; verified by mutation — restoring the
substring check fails them.
