* net: add UDP listen, resolver, DNSError, and TCP listener APIs for wasm TinyGo's net package was missing several symbols that upstream Go's js/wasm net declares, blocking builds that pull pion/transport, pion/dtls, and similar (via netbird's WASM client). Add them, backed by the existing netdev abstraction so they compile for all targets and no-op cleanly under nopNetdev (matching Go's js runtime behavior): - DNSError type (dnserror.go), copied from Go 1.26.2. - Resolver + DefaultResolver with LookupHost/LookupIP/LookupIPAddr/ LookupNetIP/LookupPort; LookupHost/LookupIP package funcs; Dialer.Resolver field for API compatibility. - UDPConn: ListenUDP, ReadFromUDP(AddrPort), WriteToUDP(AddrPort), SetReadBuffer, SetWriteBuffer. - TCPConn: CloseRead, SetNoDelay, SetReadBuffer, SetWriteBuffer, ReadFrom(io.Reader). - TCPListener: ListenTCP, AcceptTCP, SetDeadline; ListenPacket package func. - Interface: Addrs, MulticastAddrs stubs. * more complete PR for adding more net support (#64) * format unixsock
