[srijanpatel]

This pull request includes several changes to the backend codebase, primarily focused on simplifying the code and improving the handling of task and workflow data. The most important changes include removing unused imports, modifying response schemas, and updating models and methods to handle JSON data more effectively.

Codebase Simplification:

• backend/app/api/run_management.py: Removed unused imports and simplified the get_run_status function by returning the RunModel directly instead of constructing a detailed response. [1] [2]
• backend/app/execution/task_recorder.py: Removed the subworkflow parameter from the create_task method and updated the update_task method to handle subworkflow data without converting it to JSON strings. [1] [2] [3]

Schema and Model Updates:

• backend/app/models/task_model.py: Changed the subworkflow and subworkflow_output fields to use JSON data types instead of strings.
• backend/app/schemas/run_schemas.py: Updated the RunResponseSchema to include a list of TaskResponseSchema and removed the RunStatusResponseSchema class. [1] [2] [3]
• backend/app/schemas/task_schemas.py: Added a new TaskResponseSchema class to define the structure of task responses.

Dependency Updates:

• backend/requirements.txt: Updated the openai package to version 1.55.3.
