/**
 * Create markdown power plugin for VuePress.
 *
 * 为 VuePress 创建 markdown 增强插件。
 *
 * This plugin provides various markdown enhancements including:
 * - Custom containers (tabs, collapse, timeline, etc.)
 * - Code blocks enhancements (code tabs, file tree, demo)
 * - Embed syntax (video, PDF, code playground)
 * - Inline syntax (mark, subscript, superscript, footnote)
 * - Icon support
 *
 * 该插件提供多种 markdown 增强功能，包括：
 * - 自定义容器（标签页、折叠面板、时间线等）
 * - 代码块增强（代码标签页、文件树、演示）
 * - 嵌入语法（视频、PDF、代码游乐场）
 * - 行内语法（标记、下标、上标、脚注）
 * - 图标支持
 *
 * @param options - Plugin options / 插件配置选项
 * @returns VuePress plugin instance / VuePress 插件实例
 *
 * @example
 * ```ts
 * // Basic usage
 * markdownPowerPlugin()
 *
 * // With options
 * markdownPowerPlugin({
 *   tabs: true,
 *   collapse: true,
 *   pdf: true,
 * })
 * ```
