Wire pStats into sub-handlers to capture real byte counts from QUIC streams instead of the dummy listener conn. Resolve target address and validate capsule-protocol after authentication instead of before 200 response to prevent dead tunnels and unauthenticated probing. Merge pending observer events rather than replacing on consecutive failures. Add idle read timeout to TCP tunnel relay. Add doc comments on exported symbols and NewHandler.
