/**
 * Plain-Node CLI (no pnpm) — CI cascade rollup gate for the `checks` jobs of
 * ci-pr.yml and ci.yml (OPS64).
 *
 * Reads the commit statuses of the head sha via the Forgejo API and fails when
 * any of the workflow's own job statuses is failure/error (or the cascade
 * never settles / the read comes back empty). Replaces the old
 * `all(needs...)` jq, whose matrix parent result did not aggregate shards:
 * Forgejo 9.0.3 reports the LAST shard's result, so `checks` could post
 * SUCCESS with an e2e shard red (runs 604/607/610). The `needs.<job>.results`
 * array of GitHub does not exist in this runner.
 *
 * The job still runs only after every cascade job finished (`needs` +
 * `if: always()` in the workflow), so a green verdict means the whole cascade
 * settled green — the commit statuses are the same source waitForChecks
 * trusts for the merge.
 *
 *   node scripts/ci-rollup-check.mjs \

 *     --own-prefix "CI (PR) / checks" \
 *     [--ignore-prefix "CI / deploy"] \
