Copliot: Explore agents terminate without prompting or producing output

Type: Bug

I was using 5.6 Sol and set Luna as explore agent.

Steps to reproduce:
1. Modfy the setting: "chat.agent.maxRequests": 40 (eg. reduce it)
2. Trigger in the chat exploratory session, eg. search through the source code of the large Repo

Observed behaviour:
Explore agents stop without producing result if they reach the limit of requests and parent agent says there is no output

Expected result:
It should either prompt to continue or warn in advance somehow that it might not complete successfully, because otherwise tokens are just wasted.
So the main issue is this:
The Explore agents inherit this setting. Both later agents reached turn 40 while still making tool calls. A normal top-level agent can show Continue to iterate? when it reaches the limit, but a subagent cannot interact with the user, so it terminates without producing its final report.
