refactor: improve workflow test readability and maintainability

Cleanup workflow-tests.yml to address code quality issues:

✨ Improvements:
- Move assertions to same job as action execution (faster feedback)
- Clear job names that describe test scenarios
- Replace cryptic bash regex with readable validation logic
- Add informative error messages showing actual vs expected values
- Use environment variables to make assertions more readable
- Remove complex job dependencies and output passing

🎯 Benefits:
- Tests fail faster with clearer error messages
- Each test scenario is self-contained and isolated
- Easier to understand what each test is validating
- Simpler workflow structure without complex needs/outputs

The tests now clearly separate 'PR creation' vs 'no-changes' scenarios
and provide much better debugging information when they fail.
