fix: Forgot to automatically add the bidirectional communication back up to parent agents from sub-agents (i.e. need to be able to check inbox and send messages)

-    ### Teammate Messaging
-
-    Sibling agents (spawned by the same parent) can communicate directly:
-        - `agent__send_message --to <agent_id> --content \"your message\"`: Send to a running sibling
-        - `agent__check_inbox`: Check for messages from siblings or parent
-
-    Use teammate messaging when agents need to coordinate or share intermediate findings.

     ### Task Queue (for complex dependency chains)
 
     When tasks have ordering requirements, use the task queue:
