Fix macOS test failures by resolving paths in test assertions

The tests were failing on macOS due to symlink resolution differences. macOS has /var symlinked to /private/var, so tempfile.TemporaryDirectory() creates paths like /var/folders/... but ContextOptimizer resolves them to /private/var/folders/...

Fixed by calling .resolve() on base_path in the three affected tests before making assertions, ensuring path comparison works correctly across platforms.
