test(fs): unskip glob ignore pattern tests

The glob matcher pattern complexity issues have been resolved.
Both tests now pass successfully:

1. isDirEmptySync with ignore patterns - tests that .git directories
   are properly ignored when checking if a directory is empty

2. readDirNames with ignore patterns and includeEmpty: false - tests
   that directories containing only ignored files are excluded

Test results:
- isDirEmptySync ignore test: passing
- readDirNames ignore + includeEmpty test: passing

All 107 tests in test/fs.test.ts now run without skips.
