/**
* 获取本地存储的键名列表
* @param {Object} options - 查询选项
* @param {string} options.sortBy - 排序字段,默认为 "key"
* @param {string} options.sortDir - 排序方向,"asc" 或 "desc",默认为 "asc"
* @param {number} options.limit - 每页返回的记录数,默认为 100
* @param {number} options.skip - 跳过的记录数,默认为 0
* @returns {Promise<Object>} 包含键名列表和分页信息的响应对象
*
* 返回值示例:
* {
* keys: ["key1", "key2", "key3"],
* total_rows: 150,
* current_page: {
* limit: 10,
* skip: 0,
* count: 10
* },
* load_more: null // 本地存储不需要分页URL
* }
