We removed deprecated AgentOS parameters to standardize on stable naming: os_id -> id, fastapi_app -> base_app, enable_mcp -> enable_mcp_server, replace_routes -> on_route_conflict.

**Details**

- Action required: rename parameters to the stable forms
- Reduces ambiguity and future migration effort

**Who this is for:** Platform teams embedding AgentOS into services and APIs.
