What is Google ADK 2 Workflow Runtime?

Google ADK 2.0 introduces a graph engine-based workflow runtime that replaces the traditional agent executor model. This new architecture enables more flexible and scalable agent development by leveraging graph-based execution patterns. The workflow runtime provides a foundation for building complex multi-step agent behaviors with improved control flow and state management.
