this PR implements
socket.setTOS(tos)andsocket.getTOS()innet.Socket. it needed this to support DSCP tagging (QoS) for traffic prioritization, which wasn't previously exposed in the JS API. for the implementation:tcp_wrap.ccto attemptIP_TOSfirst, and fallback toIPV6_TCLASSif that fails. This handles both IPv4 and IPv6 sockets automatically without needing a separate flag.UV_ENOSYSfor now since the headers/implementation differ there.test-net-socket-tos.js) to verify input validation and ensure the values are actually set on supported platforms.Fixes: #61489
