+Subject: [PATCH] Fix Python 3.15 compatibility issues
+
+- Replace deprecated SourceFileLoader.load_module() with exec_module()
+- Add addSubTest() method to _AdaptedReporter for Python 3.15 doctest support
+- Update test expectations for Python 3.15 doctest changes:
+  - Different success/failure counts
+  - Changed error output format
