webui4frpc: 独立可用的可视化 frpc 控制器 (M0)
- 零 frp 源码依赖，单二进制 (Go + Vue3 + VueFlow + Element Plus) - 画布多对多连线，渲染 tcp/udp/http/https frpc 配置 - worker 进程管理：自愈、日志轮转、崩溃退避重启 - frpc 一键安装 (GitHub Releases) + 手动指定路径 - 三页 UI：状态(默认)/连接配置/设置 - 状态页实时节点/转发状态，节点可增删改启停 - 画布冲突检查：端口/域名冲突标红 + 弹窗拦截保存 - backend 单测覆盖 store/render/process/httpapi/install - plan.md + FRPC_FEATURES_AUDIT.md 文档
