- Add 'parent_flow' to the exclude set in Crew.copy() for forward
compatibility with older versions that had parent_flow as a Pydantic
field on FlowTrackable
- Add comprehensive regression tests covering:
- kickoff_for_each inside a @listen method of a Flow[TypedState]
- kickoff_for_each with @CrewBase pattern inside flow listeners
- crew.copy() preserving flow context in listeners
- kickoff_for_each_async in flow listeners
- akickoff_for_each in flow listeners
- Multiple kickoff_for_each across chained @listen methods
