Summary by cubic

Adds support for custom CDP headers on WebSocket connections to the browser. Enables local setups that require auth or custom proxies.

• New Features
  • Added cdpHeaders to LocalBrowserLaunchOptions.
  • CdpConnection.connect accepts headers and merges with the default User-Agent (overrides allowed).
  • V3Context and V3 pass cdpHeaders through when connecting via cdpUrl in LOCAL mode, with an integration test validating launchOptions usage.
