Root package (81.1% coverage):
- usernat: Close(), SeqAfter(), maintenance cleanup simulation
- tcp: RST, ACK handshake, data forwarding, FIN half-close, FIN+ACK,
  pure ACK sendQ advance, readFromRemote, window probe
- tcp6: SYN, RST, ACK handshake, data, FIN, data+FIN piggyback,
  flushSendQ, keepalive, short packets, BuildTCPPacket6
- listener: handleInbound RST/FIN/data, Close established/not-established
- listener6: handleInbound RST/data/FIN/ACK, Close, full IPv6 virtual
  listener handshake, short packets, deadlines, write-after-close
- udp6: newUDPConn6, handleOutbound, readLoop, short packets
- IPv6 routing through HandlePacket

vclient package (78.3% coverage):
- dns: encodeDNSName, buildDNSQuery, skipDNSName, parseDNSResponse
  (valid, ID mismatch, too short, not-response, RCODE, no answers)
- dhcp: buildDHCPMessage (Discover/Request), parseDHCPResponse
  (offer, ACK, too short, not-reply, XID mismatch, bad cookie, padding)
- arp: SetGatewayMAC, getGatewayMAC, handleARP (request/reply/errors),
  sendARPRequest, sendARPReply
- tcp: parseMSS, onRTOTimeout (SynSent/Established/FinWait1/max retries),
  handleSegment state transitions (Established→CloseWait, FinWait1→2,
  FinWait2→TimeWait, LastAck→Closed, simultaneous close, RST, data),
  Close from all states, LocalAddr/RemoteAddr
- udp: Read (single/multiple/closed), handleInbound, handleUDP dispatch,
