/**
 * @class
 *
 * ### Overview
 *
 * The `ui5-ai-versioning` component provides navigation controls for AI-generated content versions.
 * It displays the current version index and total versions, with previous/next navigation buttons.
 * This component extends ToolbarItem to participate in toolbar overflow behavior as a single unit.
 *
 * ### Structure
 * The `ui5-ai-versioning` consists of the following elements:
 * - Previous Button: Navigates to the previous version (disabled when at first version)
 * - Version Counter: Shows current version / total versions (e.g., "2 / 5")
 * - Next Button: Navigates to the nex
 * t version (disabled when at last version)
 *
 * ### Focus Management
 * The component automatically manages focus when users reach version boundaries,
 * moving focus to the available navigation button when one becomes disabled.
 *
 * ### Responsive Behavior
 * When used in a toolbar, the entire versioning component (buttons + label) will overflow
 * together as a single unit when there is insufficient space.
 *
 * ### ES6 Module Import
 *
 * `import "@ui5/webcomponents-ai/dist/Versioning.js";`
 *
 * @constructor
 * @extends ToolbarItem
 * @since 2.16.0
 * @private
