[Feature Request] Add "idle" or "waiting" status section for looping agents in overview

Question

**Bug Description**
I have still alive agents that run with `/loop` but in the agents overview, they are in the "completed" section. Some, that loop in a more tightly cadence are even "working". Add a section "idle", "waiting for next execution" or similar.
