[Feature] Agent回放请求arex-storage接口/api/storage/record/query原理

### Is there an existing issue for this?

- [X] I had searched in the [issues](https://github.com/arextest/arex-agent-java/issues) and found no similar issues.

### Description

1)、/api/storage/record/query 接口设计原理有没有详细一点的文档说明
2)、同一个请求里面并发处理，可能会多次调用一个后端接口会出现概率性的请求不到mock数据

【遇到的问题】
部分使用接口请求mock数据显示无mock数据
使用postman模拟接口请求
1、第一次请求能正常返回数据
2、再次请求就返回空了。此时清理掉redis再请求就能正确返回

### Are you willing to submit a pull request to implement this on your own?

- [ ] Yes I am willing to submit a pull request on my own!

Start by tracing the /api/storage/record/query entry point and the Redis state involved in repeated Postman requests. Reproduce the sequence where the first request succeeds but a later concurrent request returns no mock data, then document the endpoint's design and verify that repeated requests consistently return the expected mock data.
