Class UpstreamProxyConnectException

Thrown when an HTTP upstream proxy rejects a CONNECT tunnel (or otherwise fails to establish one) with a non-success response. Carries the upstream status, headers, and a bounded body snapshot for diagnostics. Relaying that response to the client is only safe before the client-facing CONNECT 200 has been committed — enable EstablishServerConnectionBeforeResponse and handle BeforeTunnelConnectFailure (issue #768).
