ERR_SOCKET_HANDLE_ADOPTED

对已经被 net.Server 或 net.Socket 接管，或已转移到其他线程的 BoundSocket 尝试操作是无效的。一旦绑定的套接字被接管或转移，其 address() 和 close() 方法就不能再使用了。

🌐 An operation was attempted on a BoundSocket that had already been adopted by a net.Server or net.Socket, or transferred to another thread. Once a bound socket is adopted or transferred, its address() and close() methods can no longer be used.
