What is the architectural difference between Dapr Workflow and Catalyst for agentic workflows?

Dapr Workflow is a building block for deterministic, replay-based workflows within the Dapr runtime. Catalyst adds an agent runner layer on top, which is framework-agnostic and handles probabilistic AI steps alongside deterministic ones. This means Catalyst can orchestrate LangGraph agents or OpenAI SDK calls with the same durability guarantees, while Dapr Workflow alone requires custom integration for agent state management.
