Send a localhost Origin header when Rozenite for Agents opens the React Native debugger WebSocket. This lets React Native 0.85 dev-middleware accept the upgrade.

What is this?
This PR fixes Rozenite for Agents failing to create a session against React Native 0.85 Metro servers. React Native dev-middleware now validates the
Originheader on debugger WebSocket upgrades, and Rozenite was opening the CDP socket without one, which caused the upgrade to be rejected with HTTP 401.Fixes #296.
How does it work?
When the agent session opens the target
webSocketDebuggerUrl, it now passes a WebSocket header withOrigin: http://localhost:<metroPort>.localhostis accepted by React Native dev-middleware's debugger WebSocket origin allow-list, so the connection can pass the upgrade check before Rozenite continues its normal CDP bootstrap flow.The session test WebSocket mock now records constructor options, and the middleware session test asserts that the debugger socket is created with the expected localhost Origin header.
Why is this useful?
This restores the first step of
rozenite agent session createfor React Native 0.85 projects, where plain HTTP target discovery succeeds but the debugger WebSocket connection is rejected before the agent can bootstrap. The change is narrow to the agent's CDP connection path and keeps compatibility with the existing Metro host and port tracking used by the middleware.
