This fork forbids headless by default (always-headed for stealth, fork.27), but CI runners have no display, so launched Chrome failed to start — every Native E2E test errored at 'Chrome Launch attempt failed'. Opt the launch-based jobs into the documented AGENT_BROWSER_ALLOW_HEADLESS=1 escape (designed for display-less servers). global-install doesn't launch Chrome, so it's untouched.
