closes # CVE-2026-40073
When reviewing the fix for the body size limit bypass in the node adapter,
I noticed the existing test suite only covered the updated code paths
(chunked encoding, valid Content-Length) but not the original bypass path.
This adds a test documenting that HTTP/1.1 requests with no
Content-Lengthand no
Transfer-Encodingheader return an empty body rather than processingoversized input.
