Interface IOriginalDestinationResolver
Resolves the original (pre-NAT) destination of an inbound QUIC connection.
When the proxy intercepts traffic via firewall/NAT redirection, the destination seen by the OS socket is the proxy's own UDP endpoint, not the origin server. This interface bridges the managed interception contract: the operator's firewall rules or packet-filter driver supply original-destination data, and this adapter exposes it to the proxy.
SNI from the QUIC ClientHello (BeforeQuicAuthenticateEventArgs.SniHostName) and
the :authority pseudo-header are validation inputs and context hints, but are not a
reliable replacement for the actual original destination obtained from the OS routing table or
packet-filter metadata, especially for pinned certificates, IP-literal URLs, or non-standard ports.
