Switching between different agents via /agent removes the queued prompts.

What steps can reproduce the bug?

1. Tell codex to spawn a sub-agent and queue a prompt in the main agent
2. Switch to the sub-agent spawned and then switch back to the main agent
3. The prompt that was queued is removed from the queue in the main agent.

This also happens for prompts queued in the subagents.

What is the expected behavior?

The queued prompts should persist
