Added comprehensive edge case tests for `getFileExtension` and `getNameWithoutExtension` methods in `FileUtils.java`.
Scenarios covered:
- Standard file with extension
- File with multiple dots (multiple extensions)
- File with no extension
- Hidden files (leading dot)
- Directory references ('.', '..')
- File ending with a dot
- Empty string
- Path with dots in directory names

These tests increase the reliability and coverage of the core utility methods used for filename manipulation.
