/**
 * `MeoNodeUnmounter` is a client-side React component responsible for performing cleanup
 * operations when a `MeoNode` instance is unmounted from the React tree.
 *
 * It leverages `useEffectEvent` to create a stable cleanup function that is called
 * when the component unmounts. This cleanup function performs the following actions:
 * - Deletes the node from `BaseNode.elementCache` using its `stableKey`.
 * - Untracks the node's mount status via `MountTrackerUtil.untrackMount`.
 * - Unregisters the node from `BaseNode.cacheCleanupRegistry` to prevent redundant
 *   finalization callbacks.
 * - Clears the `lastSignature` of the associated `BaseNode` instance to help prevent
 *   memory leaks from retained prop objects.
 * @param {object} props The component's props.
 * @param {NodeInstance} props.node The BaseNode instance associated with this component.
 * @param {ReactNode} [props.children] The children to be rendered by this component.
 * @returns {ReactNode} The `children` passed to the component.
