I often have multiple sessions running.
It would be nice to get a quick list of active sessions.
This would be nice as a whole, not just per project.

Active here can mean 2 things and I think both are useful:

1. Interacted with recently (like say... in the last hour) but may currently be idle.
2. Agent session is actively doing something and I'm waiting for a result.

Start from the /chat path in the app and trace how sessions are represented and scoped across projects. Define a quick list that covers both recently interacted sessions and sessions currently doing work, with behavior confirmed against the reported use case.
