[Requests and ideas] When importing copilot cli sessions into the app, they show up in a flat list...

When importing copilot cli sessions into the app, they show up in a flat list, even if some of them belong to the same branch/worktree. This can happen if you often use `/clear` to start a new conversation. It would be very useful to have an option to group these by worktree or branch, and show as such in the UI.

Start at the /chat path and trace the import flow for Copilot CLI sessions. Check how branch and worktree information is represented, then determine how a grouping option should appear in the UI. Done means imported sessions from the same branch or worktree are visibly grouped instead of always shown in one flat list.
