/**
 * .what = names the runner in play, and its installed version
 * .why = a break in the mint chain is a runner-version defect, so the report must
 *        name the version rather than leave a human to hunt for it
 *
 * .note = the caller declares the runner; this never detects it from env, and that
 *         is forced rather than preferred. one caller runs on the global teardown
 *         path, in the main process, where neither JEST_WORKER_ID nor VITEST is set —
 *         so an env probe would report 'unknown' from precisely the one place whose
 *         entire job is to name a version. callers in a worker already hold their
 *         runner, so the declared input costs them naught
 *
 * @returns e.g. 'jest@30.2.0', or the bare name where the manifest is unreadable
