Module orchestration 

Multi-agent orchestration: chains, graphs, DAGs, and workflows.

• Chain runs steps sequentially, passing context from one to the next.
• Graph runs nodes with conditional routing, cycles, and fan-out/fan-in (Pregel / sequential walker model).
• Dag performs topological scheduling: independent nodes execute in parallel, with cycle detection at build time (AllPredecessor model).
• Workflow extends the DAG model with field-level data mapping between nodes, inspired by Eino’s typed-field workflow engine.
