Release notes: what changed adds documentation for headers passed into localBrowser.connect() Summary by cubic Adds documentation for passing authentication headers to localBrowser.connect() (TypeScript and Python) and ConnectLocalBrowser (Go). Shows how to pass headers without putting credentials in the connection URL. Documents that headers are sent with HTTP discovery and the WebSocket connection, only forwarded to the same host and port, and never passed to the extension. Promotes the "Connecting over CDP" heading so the extension CDP URL anchor link resolves correctly. Written for commit 0a68a53 . Summary will update on new commits.
