/**
 * `debug_element` (batch-14 composite) — one-call deep-dive on a DOM element.
 *
 * Combines:
 *   - `query_dom_node` (selector → outerHTML)
 *   - `get_event_listeners` (selector → bound handlers)
 *   - `take_node_screenshot` (selector → PNG dataURL preview, optional)
 *   - `highlight_node` (selector → visual overlay, optional)
 *
 * Useful when an AI agent says "what is this `.feed-item` doing?" and wants
 * one consolidated answer instead of 4 round-trips.
