/**
 * 将 Markdown 内容转换为 HTML（同步版本）
 *
 * 同步版本的 markdownToHtml，使用相同的处理器链但以同步方式执行。
 * 适用于不需要异步处理的场景，但可能会阻塞主线程。
 *
 * @param markdown - 要转换的 Markdown 字符串
 * @param plugins - 可选的 unified 插件配置
 * @param config - 可选的渲染配置选项
 * @returns string - 从 Markdown 生成的 HTML 字符串
 *
 * @example
 * ```typescript
 * const html = markdownToHtmlSync('## 副标题\n\n- 列表项1\n- 列表项2');
 * console.log(html); // '<h2>副标题</h2><ul><li>列表项1</li><li>列表项2</li></ul>'
 *
 * // 使用配置选项
 * const htmlWithConfig = markdownToHtmlSync(
 *   '[链接](https://example.com)',
 *   undefined,
 *   { openLinksInNewTab: true }
 * );
 * ```
 *
 * @throws {Error} 当转换过程中发生错误时返回空字符串
 *
 * @remarks
 * - 建议在可能的情况下使用异步版本 `markdownToHtml`
 * - 同步版本可能影响用户界面响应性
