Note

Low Risk
Type-only additions and a patch version bump with no runtime or security logic changes in this repo.

Overview
Exposes browser network policy options on session create and launch-state types so SDK consumers can configure outbound traffic when starting or inspecting sessions.

CreateSessionParams and SessionLaunchState now include optional allowInternetAccess (boolean), allowOut (string allowlist), and denyOut (string denylist). Package version is bumped to 0.91.8; there is no new client logic beyond typing—these fields pass through to the API like other session flags.
