Previously, coverage analysis was incorrectly using keywords from all
existing tests, causing false positives where untested issues showed
coverage percentages instead of 0%.
Changes:
- Only count tests specifically related to the analyzed issue
- Return 0% coverage when no issue-specific tests exist
- Maintain accurate coverage calculation for tested issues
This ensures that Issue #3 correctly shows 0.0% coverage instead of
33.3%, while Issue #11 still correctly shows 100.0% coverage.
