feat(browser): add extraArgs config for custom Chrome launch arguments

Browse Source 
Adds a `browser.extraArgs` config option (string array) that is appended
to Chrome's launch arguments. This enables users to add stealth flags,
window size overrides, custom user-agent strings, or other Chrome flags
without patching the source code.

Example config:
  browser.extraArgs: ["--window-size=1920,1080", "--disable-infobars"]
