Refactor Assistant struct to replace Flows with Workflow and update cloning logic

- Replaced the Flows field in the Assistant struct with a Workflow field to better represent the assistant's functionality.
- Updated the Clone method to perform a deep copy of the Workflow instead of Flows.
- Adjusted related test cases to reflect the changes in the Assistant struct and ensure proper functionality.
