[Feature Request] Restore `/rename` command support in agents overview page

Bug Description
we used to be able to directly open a new NAMED session from the agents overview page (launching claude via "claude agents") by stating /rename My new session name straight from the agent overview input line. Now it complains that /rename is not available there and we first must start a new session.

It is super annoying to not being able to start an agent with a clean naming... by applying a clean name from the start, before you even set it up to do anything, the whole list of agents remains so much more maintainable.

Can you PLEASE bring this capability back ?
