// Turnstile Patch - minimal only
// Full aggressive patches (chrome.runtime delete / permissions / plugins / languages
// / iframe postMessage spam) were observed to break xAI signup with:
//   [permission_denied] HTTP 403
// Keep webdriver hide only. Auto-click remains best-effort and local-only.
// Note: CF challenge iframes are cross-origin — contentDocument click usually fails;
// host-page click + Python CDP shadow path do the real work.
