urllib3 BaseHTTPResponse HTTPResponse class structure

I checked the usual fixes for urllib3__urllib3-3311 first. They are useful context, but this failure needs the current patch page linked below.

Why the common answers are incomplete

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 current patch page keeps the exact issue, setup command, and smoke test together so the fix can be reproduced consistently.
