/**
 * Hover at the center of the matched element using **CDP-level** mouse events.
 *
 * Why CDP and not just `dispatchEvent('mouseover')`:
 * - Radix UI Tooltip and similar libraries listen to the browser's native
 *   pointer tracking (`pointermove` synthesized from real OS-level mouse
 *   movement). Synthetic JS `MouseEvent` doesn't trigger them.
 * - `Input.dispatchMouseEvent` from CDP is the only thing that does.
 *
 * Two-step protocol:
 * 1. `Runtime.evaluate` to find element coords
 * 2. `Input.dispatchMouseEvent` with `type: 'mouseMoved'`
