+ * SeekDB 键值存储类
+ *
+ * 用于存储同步进度、配置等键值数据
+ *
+ * 使用方法:
+ *
+ * 1. 基本操作
+ *    - 设置键值: set('sync_last_id', 12345);
+ *    - 获取键值: $lastId = get('sync_last_id', 0);
+ *    - 删除键值: delete('sync_last_id');
+ *
+ * 2. 批量操作
+ *    - 批量设置: batchSet(['key1' => 'value1', 'key2' => 'value2']);
+ *    - 批量获取: $values = batchGet(['key1', 'key2']);
