/**
 * A hook that manages focus behavior for interactive UI components like menus or modals.
 *
 * This hook handles focus management by storing the previously focused element when
 * a component opens, focusing the first focusable element within the component,
 * and restoring focus to the original element when the component closes. This is
 * essential for accessibility and keyboard navigation.
 *
 * @param isOpen - Boolean indicating whether the component is open.
 *                 When true, captures current focus and moves focus to the first
 *                 focusable element in the menu. When false, restores focus to
 *                 the previously focused element.
 * @param menuRef - React ref object pointing to the container element that
 *                  contains the focusable elements to manage.
 *
 * @returns An object containing:
 *   - getFocusableElements: Function that returns all focusable elements
 *     within the menu container using the standard focusable selector.
 *
 * @example
 * ```tsx
 * function DropdownMenu({ isOpen }: { isOpen: boolean }) {
 *   const menuRef = useRef<HTMLDivElement | null>(null)
 *   const { getFocusableElements } = useFocusManagement(isOpen, menuRef)
 *
 *   return (
 *     <div ref={menuRef}>
 *       <button>Option 1</button>
 *       <button>Option 2</button>
 *     </div>
 *   )
 * }
 * ```
