feat: 新增 JSONL 存储格式支持,默认存储格式改为 jsonl
JSONL(JSON Lines)每行一个 JSON 对象,采用 append 模式写入, 无需读取已有数据,大数据量下性能远优于 JSON 格式。 - 新增 AsyncFileWriter.write_to_jsonl() 核心方法 - 7 个平台新增 JsonlStoreImplement 类并注册到工厂 - 配置默认值从 json 改为 jsonl,CLI/API 枚举同步更新 - db_session.py 守卫条件加入 jsonl,避免误触 ValueError - 词云生成支持读取 JSONL 文件,优先 jsonl 回退 json - 原有 json 选项完全保留,向后兼容 - 更新相关文档和测试
