Pull request overview
This PR adds comprehensive test coverage for shared state behavior in subworkflows, documenting both working and isolated state scenarios. The tests verify that shared state operates correctly within a subworkflow while also documenting the current limitation where state is isolated across parent/subworkflow boundaries (issue #2419).
Changes:
- Added test file documenting shared state behavior in subworkflows with three executor classes that pass data through shared state
- Added two test methods validating shared state works within subworkflows and is isolated across boundaries
- Implemented helper methods to run different workflow configurations for testing state persistence
