Technical summary

urllib3 BaseHTTPResponse and HTTPResponse class structure needs to preserve the expected inheritance/API relationship.

Keep HTTPResponse as a concrete BaseHTTPResponse subclass and ensure imports/type checks observe that structure.

This issue is about class structure, so compatibility tests should assert isinstance(response, BaseHTTPResponse).

The snippet uses native project logic; the configured response class is normalized before urllib3 instantiates the connection response. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import urllib3; print('smoke test OK')"
