/**
 * CDP client — implements IPage by connecting directly to a Chrome/Electron CDP WebSocket.
 *
 * Fixes applied:
 * - send() now has a 30s timeout guard (P0 #4)
 * - goto() waits for Page.loadEventFired instead of hardcoded 1s sleep (P1 #3)
 * - Implemented scroll, autoScroll, screenshot, networkRequests (P1 #2)
 * - Shared DOM helper methods extracted to reduce duplication with Page (P1 #5)
