Example AgentOS app with a custom FastAPI app with conflicting routes.

"""
Example AgentOS app with a custom FastAPI app with conflicting routes.

This example demonstrates the `on_route_conflict="preserve_base_app"` functionality which allows your
custom routes to take precedence over conflicting AgentOS routes.

When `on_route_conflict="preserve_base_app"`:
- Your custom routes (/, /health) will be preserved
- Conflicting AgentOS routes will be skipped
- Non-conflicting AgentOS routes will still be added

When `on_route_conflict="preserve_agentos"` (default):
- AgentOS routes will override your custom routes
- Warnings will be logged about the conflicts
