会话历史记录数太多会卡死

当前设置的历史保留天数 7天，历史大小10000，在跟hermes对话修改代码时，经常会出现该会话无法响应，无法输入任何字符，如果尝试去关掉该会话，整个windterm程序都会变成无响应，基本上每天都能遇到几次

Reproduce the freeze while chatting with Hermes using a 7-day history retention period and a history size of 10000. Observe whether the session becomes unable to accept input and whether closing it makes WindTerm unresponsive. Done means sessions remain responsive and the application can close them without hanging under these conditions.
