…e_chat - Implements lightweight UDP-based discovery beacon (CLanDiscoveryBeacon) and client utility (CLanDiscoveryClient) on port 27015. - example_chat server advertises its listen port and responds to discovery queries. - example_chat client auto-discovers and connects to the local server when no address argument is provided. - Responds to mobile/external GNS_PING probes with GNS_PONG. Closes ValveSoftware#82
…dress ranking - Eliminate double-close and cross-thread socket data race in beacon teardown. - Retransmit discovery query every 500ms to tolerate packet loss on wireless LANs. - Prioritize routable physical LAN interfaces over internal container bridges. - Add ScopedWinsockInit guard on Windows.
