/**
 * Slow-test finder: runs the full suite (via the shared test harness) and
 * treats the 500ms slow-test threshold as a hard failure instead of a quiet
 * end-of-run warning, so a slow test surfaces as a crashing, slowest-first list
 * rather than a notice you might miss. Exits 1 when any test is too slow; 0
 * when none are. Coverage is skipped — it isn't needed to find slow tests and
 * only slows the run.
