/**
 * 首页轮播图数据接口
 * @returns 轮播图数据列表
 * 
 * 替换真实接口说明：
 * 1. 替换真实接口时，需要修改以下内容：
 *    - 将模拟数据替换为真实接口调用
 *    - 添加错误处理
 *    - 添加接口参数处理
 *    - 添加数据转换逻辑
 * 
 * 2. 真实接口示例：
 *    const response = await $fetch('https://api.example.com/carousel', {
 *      method: 'GET',
 *      headers: {
 *        'Authorization': 'Bearer your-token',
 *        'Content-Type': 'application/json'
 *      },
 *      params: {
 *        page: 1,
 *        limit: 10
 *      }
 *    })
 * 
 * 3. 错误处理示例：
 *    try {
 *      const response = await $fetch('...')
 *      return {
 *        code: 200,
 *        data: response.data,
 *        message: '获取轮播图数据成功'
 *      }
 *    } catch (error) {
 *      return {
 *        code: 500,
 *        data: [],
 *        message: '获取轮播图数据失败'
 *      }
 *    }
 * 
 * 4. 数据转换示例：
 *    const transformedData = response.data.map(item => ({
 *      id: item.id,
 *      title: item.title,
 *      image: item.imageUrl,
 *      link: `/products/${item.productId}`
 *    }))
 * 
 * 5. 接口参数处理示例：
 *    const query = getQuery(event)
 *    const page = Number(query.page) || 1
 *    const limit = Number(query.limit) || 10
