What
Activity tracking for nested agents moved from a single module-level map into a class that keys state by chain, evicts old keys under a cap and cleans up that key's heartbeat and idle timers. Nothing changes on screen, but concurrent agent chains are now accounted for separately instead of sharing one global state.
Details
Listeners were split into one for the main loop and one for dropped nested chains.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
