+Subject: [PATCH] tests: Fix test_module for Python 3.14
+
+Python 3.14 changed argparse to lazily import _colorize during
+ArgumentParser.__init__, triggering a chain of imports
+(_colorize -> dataclasses -> inspect -> tokenize) that ends with
+`from builtins import open`. The class-level mock.patch.dict on
+sys.modules with clear=True removed builtins from sys.modules,
+causing this import to fail with ImportError.
+
+Narrow the mock scope to wrap only the take_action call rather
+than the entire test class, so get_parser/argparse initialization
+runs with an unpatched sys.modules while take_action still
+iterates the controlled set of fake modules.
