Motivation and Context
Implements AG-UI (Agent-User Interaction) protocol support for the Python Agent Framework, enabling standardized streaming communication with AG-UI-compatible frontends. This is the Python equivalent of .NET PR #1776.
The AG-UI protocol is an open, event-based protocol that standardizes how AI agents connect to user-facing applications. Without AG-UI support, Python agents cannot interoperate with the growing ecosystem of AG-UI-compatible frontends (CopilotKit, LangGraph Studio, etc.).
