Add vclient.Client.Listen: net.Listener for virtual TCP servers

The vclient can now accept incoming TCP connections via a standard
net.Listener interface, enabling virtual server applications.

New types:
- Listener implements net.Listener (Accept, Close, Addr)
- Client.Listen(network, address) creates a Listener on a port

Implementation:
- Client tracks listeners by port in a listeners map
- handleTCP intercepts SYN packets for listener ports
- Creates vtcp.Conn via AcceptSYN, wraps in TCPConn, queues on acceptCh
- Subsequent packets dispatched normally via connKey lookup
- Listeners cleaned up on Client.Close()

Tests:
- TestClientListen: two vclients wired directly (no slirp stack),
  echo server via Listen/Accept, data integrity verified
- TestClientListenDuplicate: double-listen same port fails
- TestClientListenClose: Accept returns error after Close
