pywidevine's serve module expects users to be a dict mapping secret keys to user objects with devices and username, not a simple list.
This was causing TypeError when accessing CDM endpoints.
Very early dev work, more changes will be active in this branch.
- Implement download queue management and worker system
- Add OpenAPI/Swagger documentation
- Include download progress tracking and status endpoints
- Add API authentication and error handling
- Update core components to support API integration
