Package history records per-peer time-bucketed metrics for the PathInfoExpand UI.

Package relay provides decentralized peer-to-peer traffic forwarding through Hysteria 2 tunnels.

Package sniff recovers an application-layer hostname from the first bytes a client sends after a proxy CONNECT/SOCKS5/SS exchange, so the proxy can override an IP-form destination (typically a DNS-poisoned IPv4 the client resolved before reaching us) with the real hostname before its own net.Dial.
