Problem

The current CdpClient.send() sends a command and reads the next WebSocket message as the response. But CDP can send events (no id field) between command responses. If Chrome pushes an event before our response, we'll return the wrong data.

Fix

Implement response correlation:

1. Parse the id field from each received message
2. If it matches our sent command ID → return as response
3. If it's an event (no id) → buffer/skip and read next message
4. Add timeout for response waiting

Inspiration

vercel-labs/agent-browser handles this via Playwright's built-in CDP session management which correlates responses internally.
