Describe the bug

[assistants API] How long are the validity periods of Messages and Runs?
The deletion API of Assistants and Threads, my understanding is that it will always exist if it is not actively deleted.
As for Messages and Runs, I’m not sure how long they last.
【assistants API】Messages、Runs的有效期是多久？
Assistants、Threads的删除的API，我的理解是不主动删除一直存在
而Messages、Runs的是多久不太确定
