Invisible_playwright: Stealth Firefox that passes every bot detection test

SMRTR summary

invisible_playwright is a C++-patched Firefox that integrates fully with Playwright and beats the toughest browser fingerprint detectors, scoring 0.90 on reCAPTCHA v3 and zero lies on CreepJS. Unlike commercial anti-detect browsers that rely on detectable JavaScript overrides, it spoofs at the engine level — Navigator, WebGL, Canvas, WebRTC, and more — leaving no shim artifacts for bot detectors to latch onto.
