docs: add CloakBrowser stealth browser example

[Cloak-HQ]

Description

Add CloakBrowser integration example, following the same pattern as the existing Camoufox example.

CloakBrowser is a patched Chromium binary with source-level fingerprint modifications that passes Cloudflare Turnstile, reCAPTCHA v3 (0.9 score), and common bot detection checks where stock Chromium and playwright-stealth get blocked.

The integration uses a custom PlaywrightBrowserPlugin that swaps the default Chromium for CloakBrowser's binary. Same plugin pattern as Camoufox — override new_browser(), return a PlaywrightBrowserController.

• docs/examples/playwright_crawler_with_cloakbrowser.mdx — docs page

Testing

Tested on Linux x64 with Crawlee 1.5.0. The plugin launches CloakBrowser's binary, all stealth checks pass (webdriver=false, spoofed GPU/platform/plugins/hardwareConcurrency). Zero failed requests.

Checklist

• CI passed

Hi @Cloak-HQ, thanks for your PR. We will discuss it with the team and let you know.

We believe this would better fit in the Avoid getting blocked guide, under the Camoufox 🙂.

[Cloak-HQ]

Thanks for the feedback! Moved the example into the "Avoid getting blocked" guide as a new section after Camoufox. Also added context on how CloakBrowser differs from the other options on the page (source-level C++ patches vs runtime JS overrides, Chromium-based vs Firefox).

Let us know if the placement and wording work for you, or if you'd like any changes.
