Support IPv6

Start with app/Factory.php around line 204 and app/Commands/ServeCommand.php around line 51, then reproduce the reported command on Debian. Trace how the IPv6 address is passed to React SocketServer and verify the server can listen successfully on IPv6 port 8080 without the shown getaddrinfo error.
