读取聊天消息。支持按 sid 首次加载会话消息、按 mid 游标翻页、按 uid 查询某客户消息。适用于查看当前会话上下文、查看历史会话命中词前后文、按 UID 拉取某段时间内消息并总结诉求/投诉/售后问题。已知 uid/sid/mid 时直接调用本工具，不要先搜索。约束：sid、mid、uid 至少传一个；传 mid 时建议同时传 direction；按 uid 查询时 start_time/end_time 可选；size 最大 20。时间语义：start_time/end_time 是消息发生时间过滤，不是会话开启时间。

|---|---|---|---|
| sid | string | no | 会话 ID。首次按会话加载消息时传。 |
| mid | string | no | 消息 ID。按游标翻页时传；传 mid 时建议同时传 direction。 |
| uid | string | no | 知你侧客户 UID。按客户查询消息时传，可结合 start_time/end_time 限定消息发生时间。 |
| direction | string | no | 翻页方向。backward 表示更早消息，forward 表示更新消息。 |
| start_time | number | no | 查询消息开始时间，秒级 Unix 时间戳。按 uid 查询时可选，表示消息发生时间。 |
