Add comprehensive debug logging for CI test failures

- Check if services data loads properly from embed files
- Verify service definitions exist in loaded data
- Show available services when service not found
- Check testdata files exist and have proper size
- Show which files are analyzed for each language
- This will help identify the root cause of CI failures
