Serving an AgentOS with an Auto-Populated Registry
==================================================
This is the same idea as ``auto_populate_registry.py``, but served as an app so
you can see the discovered components over the API.
No registry is passed to AgentOS. After the app starts, the components used by
the team members are available at:
GET /registry?resource_type=model
GET /registry?resource_type=tool
GET /registry?resource_type=db
A registry passed explicitly is still honoured: anything you declare is kept,
and the discovered components are merged in (deduplicated by id/name).
