Hi there! The AgentManager hasn't been in use for a few weeks – disabled because it had more issues than added value – and was just removed by #4900. As such, this PR can't be merged anymore. Still, thanks for submitting! And sorry we didn't get to it earlier.

We'll add back support for sub-agents in the near future, but this time they will be fully-featured agents instead of simple sub-chats. :)
