Lighthouse user flows can dispose of pending navigation waits

If a Lighthouse user-flow navigation fails, call `flow.dispose()` in the catch path to cancel pending navigations and clean up wait conditions. Closing the Puppeteer page also disposes of those conditions automatically, according to the v13.5.0 release note.

try { await flow.startNavigation(); await page.goto('https://invalid-url.dev/'); await flow.endNavigation(); } catch (error) { flow.dispose(); console.error("Navigation failed:", error); }
