Fix CI failures: workflow guidance logic and linting issues

- Fix workflow guidance to properly handle CREATED state tasks requiring user feedback
- Fix regex pattern in test_prompt_loader.py to use raw string for linting compliance
- Format workflow_guidance.py to meet code style requirements

The workflow logic now correctly prioritizes task state over task size,
ensuring all CREATED tasks get user feedback regardless of size.
