feat(platform-web): expose ignoreDefaultArgs in browser config

Forward Playwright's launch option through WebBrowserConfigSchema so
users can disable or override Playwright's default Chromium/Firefox/WebKit
launch arguments (e.g. removing --enable-automation, or providing a custom
arg set) without having to fork the runner.

Accepts either a boolean or a string[] of default args to ignore, matching
Playwright's LaunchOptions.ignoreDefaultArgs signature.
