 * Tracks scroll position and deltas.

 * @remarks
 * This hook listens to scroll events on the window or a specified container.
 * It debounces the callback to improve performance.
 *
 * @param fn - The callback to execute on scroll.
 * @param options - Configuration options (container, timeout).
 *
 * @example
 * ```tsx
 * useScrollPosition(({ y, delta }) => {
 *   console.log("Scrolled to", y, "Delta", delta.y);
 * }, { timeout: 100 });
 * ```
