Resolves PermissionError on Windows during temporary directory cleanup by restoring the original working directory before the TemporaryDirectory context manager exits. On Windows, you cannot delete a directory that is the current working directory. The tests were calling os.chdir(tmpdir) and then attempting to clean up the directory when the context exited, causing: - PermissionError: [WinError 32] The process cannot access the file because it is being used by another process - PermissionError: [WinError 5] Access is denied Solution: Wrap test logic in try/finally blocks that save and restore the original working directory, allowing Windows to successfully delete temporary directories during cleanup. Fixes #40 (Windows CI failure in test_dict_flattening.py)

Apply test_dict_flattening.py from PR #46 which includes: - Windows file deletion fix (try/finally blocks) - Pandas availability check (try/except import) - pytestmark to skip tests when pandas unavailable This ensures compatibility with environments where pandas may not be installed while maintaining the Windows file cleanup fix.
Resolved conflicts in tests/test_dict_flattening.py by: - Removing PANDAS_AVAILABLE checks (pandas is now required) - Keeping Windows file deletion fixes with os.getcwd()/os.chdir() pattern 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
