🐛 Bug Description

When using subagents with tools that have HITL enabled (or the default ask questions tool), they will get stuck since the tool will require human input and there's no way to provide them. This results in them returning "" an empty response. This persist for the entire session (because the session has a pending state attached) and the only way to fix this is to start a new session.

🔄 Steps To Reproduce

1. Setup an agent with HITL tools
2. Setup another agent with the first agent as subagent
3. Ask the main agent to send a request to the subagent to use HITL tools

🤔 Expected Behavior

Approval should bubble up the chain of requests and require user input in the top-level chat
