Add workflow and fixtures to test the behavior of fail-on-error and
fail-on-empty parameters across different scenarios:
- Passing tests with fail-on-error true/false
- Failing tests with fail-on-error true/false
- Empty results with fail-on-empty true/false
Scenario 4 (failing tests + fail-on-error=false) is expected to fail
until issue #217 is fixed, documenting the bug where check conclusion
shows 'success' even when tests fail.
The workflow outputs a GitHub Actions summary with a markdown table
showing all test results.
