What
The supervisor that runs child sessions now records what each child is doing between turns, which is groundwork for surfacing that state rather than something visible yet.
Details
It classifies follow-up turns against new ones, notes whether a child has stopped at a prompt or is still working, and records child exit.
Stream events flagged as coming from a sub-agent are now ignored by this path.
Evidence
child parked at a prompt
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
