Stealth browser fallback using CloakBrowser (custom-compiled Chromium with C++ source-level fingerprint patches). Use when the built-in browser tool or Chrome DevTools fails due to bot detection, Cloudflare/Turnstile walls, reCAPTCHA, 403/429/"access denied"/"are you human" interstitials, or empty/ blocked responses. Also use when the user asks for "cloakbrowser", "stealth browser", or to bypass a block.
