Problem: If you use the Orchestrator with several helper agents, the list fills with agents you never chat with.
Idea: a per-agent setting, “Delegation only”, that keeps the agent out of the sidebar and chat picker. The agent stays available to the Orchestrator and in Settings, Agents. A “Show hidden agents” toggle brings them back.
Why: a shorter list, and fewer chats by mistake with agents that have narrow tools or permissions.
Not asking for: any change to how delegation works.
