Protocol stack trait for network protocols

This trait defines the interface for protocol stack implementations. ABI modules can implement this to provide TCP/IP, UDP, or other protocol support.

§Example: TCP/IP Stack

struct TcpIpStack {
    // TCP/IP implementation details
}

impl ProtocolStack for TcpIpStack {
    fn domain(&self) -> SocketDomain {
        SocketDomain::Inet
    }

    fn create_socket(&self, socket_type: SocketType, protocol: SocketProtocol)
        -> Result<Arc<dyn SocketObject>, SocketError> {
        match (socket_type, protocol) {
            (SocketType::Stream, SocketProtocol::Tcp) => {
                Ok(Arc::new(TcpSocket::new(self.clone())))
            }
            (SocketType::Datagram, SocketProtocol::Udp) => {
                Ok(Arc::new(UdpSocket::new(self.clone())))
            }
            _ => Err(SocketError::NotSupported),
        }
    }

    fn process_incoming_packet(&self, packet: &DevicePacket) -> Result<(), SocketError> {
        // Parse IP header, route to appropriate socket
        // ...
        Ok(())
    }
}
