Regression test request: websocket / upgrade safety edge cases

[TheWatcher01]

Please add regression tests for the recent high-severity undici WebSocket and upgrade-path advisories (permessage-deflate, invalid server_max_window_bits, CRLF injection / smuggling, and related decompression cases).

Our audit now resolves undici 6.24.0 via @qdrant/js-client-rest, and we want a stable test guard for future releases.

On the technical merit front, there should be regression tests for each change. If any cases are missing, please be specific.

I would recommend you rethink how you approach open-governed Open-Source software: you cannot "want" anything from volunteers. We do not work for you. Be thankful this exists.
