✨ feat: 新增设备信息与额外路由设置，支持设备名广播及TUN显式禁用

- 设置页新增设备名称(单行)、设备描述(多行)、额外路由(CIDR列表)设置项
- RouterInfo 广播携带 deviceName，并在拓扑图节点与节点概览中展示；deviceDescription 保持本地概览显示
- 拓扑图节点标签支持多行文本绘制
- 节点概览面板新增 IP 地址及设备详情展示
- 支持将 TUNName 设为 null/"null"/空字符串时完全跳过 Wintun 虚拟网卡创建
- .classpath 容器改为标准 JavaSE-25 执行环境以同时兼容 JDK 25 与 26
- 新增 AGENTS.md 与 VS Code 调试及运行配置

BREAKING CHANGE: RouterInfo 在序列化末尾追加了 deviceName 字段(writeUTF)，新旧版本节点混连时路由协议解析异常，需同步升级
