 * Wrap a callback so successive calls within `delayMs` collapse into a

 * `.cancel()` (drop pending) and `.flush()` (run pending immediately).
 *
 * The latest `callback` reference is always invoked — internal ref-sync
 * means re-renders that pass a new closure don't reset the timer.
 *
 * @example
 *   const onChange = useDebouncedCallback((value: string) => {
 *     void search(value);
 *   }, 250);
