/**
 * Menu Item Group - A container for organizing related menu items into labeled sections within a menu.
 *
 * @description
 * The Menu Item Group component provides a way to organize related menu items into logical sections
 * with an optional header label. It supports both horizontal and vertical orientations, text overflow
 * handling, and automatic item counting. The group helps create clear visual hierarchies and improves
 * menu navigation by categorizing related actions or options together. It's commonly used to separate
 * different types of actions or to create labeled sections within dropdown menus and context menus.
