mcproxyctl status now shows individual routes per listener with hostname, backend, mode, and re-encrypt indicator. Proto, gRPC server, client library, and CLI all updated. Default gRPC socket path moved from /var/run/mc-proxy.sock to /srv/mc-proxy/mc-proxy.sock to match the service data directory convention.
