- 协议: InitMessage 增加 ip6/prefix6/server_ip6 字段(omitempty,向后兼容) - TUN: Device 接口新增 ConfigureIPv6, macOS 用 ifconfig inet6, Linux 用 ip -6 addr add - 路由: full 模式自动添加 ::/1+8000::/1, v6 服务器旁路 /128, resolveHosts 双栈解析 - 会话: setupTUN 解析 v6 字段并配置 TUN+路由, connectOnce 传 v6 给 stats/日志 - 统计: SetConnected(ip,ip6), Snapshot.AssignedIP6 - DB: connection_logs 增加 assigned_ip6 列 + migrateV3 幂等迁移 - UI: 状态卡片新增独立 IPv6 行, 始终可见(未获取显示 IPv6: —) - 文档: 同步 client-development.md 至服务端 IPv6 版本
