When I run a /fleet command after getting a plan, in this instance is spawned off 6 background agents, but the UX renders it differently than if you had asked GH Copilot app in the chat to spawn off child sessions.

I can see that there are 6 background threads running in the pill above the chat window, but the parent session does not show a "working" gif, nor do any of those background sessions show as child sessions underneath the parent.

It'd be nice if that experience was unified, since they are effectively the same thing

Reproduce the /fleet flow in /chat after a plan is generated and compare it with spawning child sessions from the GitHub Copilot app chat. Inspect the background-thread pill, parent working indicator, and child-session list; done means both flows present the same parent/child session UX.
