 * Playwright's `executablePath()`, checks it exists on disk, then performs a
 * real `launch({ headless: true })` + `close()` smoke-test under a timeout.
 *
 * A browser is only healthy when it actually launches: on bare Linux the
 * binary can be on disk yet fail at launch because OS shared libs (libnss3,
 * libgbm, ...) are missing. existsSync alone would lie; the launch smoke-test
 * is the honest "does it work" result.
