/**
 * CDP (Chrome DevTools Protocol) handler for the Browser Agent tool.
 * Provides WebSocket endpoint for frontend to control Chrome tabs via CDP.
 *
 * Flow:
 * 1. Frontend connects to ws://localhost:48242/cdp?port=9222
 * 2. Bridge connects to Chrome's CDP WebSocket
 * 3. Frontend sends commands (listTabs, screenshot, click, type, scroll)
 * 4. Bridge forwards to Chrome and returns results
