v0.22.2

Fixed

• A streamed answer reaches an HTTP/1.1 workload with its end marked.
  When the gateway substituted into a request whose destination streamed
  its answer over HTTP/2, as a model's is, a workload that spoke HTTP/1.1
  read the whole stream and then waited forever for the connection to
  close. Claude Code hung on its first request this way. The stream is
  now sent chunked, and the connection serves the next request.
