fix: handle empty string executable names in swift_package_list

- Fix test failure by treating empty strings as falsy for default naming
- Use logical OR instead of nullish coalescing for this specific case
- Add ESLint disable comment with explanation for intentional usage
- All tests now pass (1602 passing, 3 skipped)
- Maintains 100% ESLint compliance (0 errors, 0 warnings)
