handle_launch's fresh-launch path (the path `--launch open <url>` takes) never
called apply_stealth_to_browser — only the launch FLAGS were applied (e.g.
--disable-blink-features=AutomationControlled, which is why navigator.webdriver
was already false). As a result the 32 JS fingerprint patches and the
Emulation.setUserAgentOverride HeadlessChrome→Chrome UA strip NEVER ran on a
launched browser: navigator.userAgent kept the HeadlessChrome marker (a
longstanding bug — identical on the prior prebuilt binary).
Add the apply_stealth_to_browser call after launch (the auto_launch path
already had it; only the explicit-launch path was missing it).
Verified, FullLaunch headless:
- navigator.webdriver === false, navigator.userAgent => Chrome/<v> (no Headless)
- new tabs and the initial page both clean
- bot.sannysoft.com: 0 failed / 31 passed
