When grouping sessions by "last updated" can we still show which repo they are associated with in some way?

I like having recent ones on top, but I need to see the repo context at a glance in some way, so flat sessions are not great and I'm forced to use project grouping for this.

从 /chat 会话列表开始，检查现有的“last updated”视图和项目分组视图是如何呈现的。完成的定义是：会话仍按“last updated”排序，同时无需项目分组即可一眼看到其关联的 repository 上下文；issue 中未指定具体文件或测试。
