description: >-
  Provide a libnode pack for the Node island tests and export
  SCRIPTC_LIBNODE: restored from the cache, or on a miss assembled from the
  pinned, checksum-verified inputs in packages/libnode-common/dev-pack.json
  for the runner's platform (a prebuilt libnode and Node's headers; the
  bridge builds in seconds). Temporary until the NI-13 packs exist. Fails
  the job if no pack results: the island tests must never skip in CI.
