/**
 * Plain-Node CLI (no pnpm) — OPS104 trigger 2. Runs hosted after a green
 * `deploy-staging`: if `main` advanced while the run was in flight, dispatch
 * a new `deploy.yml` from the new head. `workflow_dispatch` is the documented
 * anti-recursion exception, so the built-in `GITHUB_TOKEN` (`actions: write`)
 * suffices — no PAT.
 *
 * Fail-red (OPS104 D6): a failure here would leave staging stale in silence —
 * exit 1 makes it visible (the operator re-dispatches by hand).
