END_STREAM.Reject:
1xx) response headers carryingEND_STREAMEND_STREAMThis aligns the client-side response handling with RFC 9113 section 8.1:
https://www.rfc-editor.org/rfc/rfc9113.html#section-8.1
RFC 9113 states that a HEADERS frame carrying an informational status code together with
END_STREAMis malformed, and that trailer fields are carried in a field block that terminates the stream.
