 * Detects if the element matching the given selector moves in the viewport.
 * Snapshots the element's position via `getBoundingClientRect` and watches for
 * changes using a `ResizeObserver` plus window `scroll` and `resize` listeners.
 * Resolves when movement is detected. Falls back to completing immediately if
 * the element is missing.
 *
 * Cleanup runs automatically when the fiber is interrupted (e.g. by
 * `Effect.raceFirst`), removing the observer and event listeners via
 * `AbortSignal`.
 *
 * @example
 * ```typescript
 * Dom.detectElementMovement('#menu-button')
 * ```
