Summary of Changes

Hello @slin1237, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly refactors the project's workflow management system by extracting the generic workflow engine into its own top-level module and relocating domain-specific workflow steps to a dedicated core/steps module. This change improves the overall architecture by creating a clearer separation between reusable infrastructure and application-specific logic, enhancing modularity and maintainability.

Highlights

  • Workflow Engine Extraction: The generic, reusable components of the workflow engine have been moved from src/core/workflow to a new top-level module, src/workflow, enhancing modularity.
  • Domain-Specific Steps Relocation: Application-specific workflow steps, previously located in src/core/workflow/steps, have been relocated to src/core/steps, clearly separating domain logic from the generic engine.
  • Comprehensive Import Updates: All affected files across the codebase have been updated to reflect the new module structure, ensuring correct referencing of the moved components.
  • Improved Modularity and Separation of Concerns: This refactoring establishes a cleaner separation between the reusable workflow engine and the application's specific business logic, making the system more maintainable and extensible.

Code Review

This pull request is a large-scale refactoring to separate the generic workflow engine from domain-specific workflow steps. The changes are well-executed, with file moves and import updates applied consistently throughout the codebase. I've identified a few minor opportunities to improve code style by moving use statements from within functions to the top of their respective files for better organization and consistency.
