mrlee 2f59f5adc4 feat(agent): agent 0.10.0 新增资源/日志/配置回读端点,前端接入 VPS 资源与公网 Nginx 日志(v1.2.4)
agent 0.10.0:新增 GET /api/v1/metrics(资源采集,复用 internal/sysinfo;CPU 两次采样差值 + 1 秒内复用上次结果)、GET /api/v1/logs/nginx(日志尾部,路径白名单来自 nginx -T / 环境变量 / 默认目录,32KB 块倒读、单行 4KB 截断、上限 2000 行)、GET /api/v1/frps/config(frps.toml 回读,256KB 上限)

internal/sysinfo:补 LoadAvg 与 UptimeSeconds(Linux /proc/loadavg 与 /proc/uptime、Windows GetTickCount64、其它平台空值)

应用侧:AgentClient 三个只读方法;request 错误改为带状态码的 statusError,新增 ErrAgentEndpointMissing,把 404/405 统一转成「agent 版本过低需 ≥ 0.10.0」提示;补 service/handler/router

前端:公网 Agent 页「VPS 资源」横排带(占满环境与依赖整行);日志中心「公网 Nginx」页签;frps 同源配置弹窗「比对 VPS 实际文件」

二进制:内嵌 fonu-agent-linux-amd64 / arm64 用新代码重编;VERSION → 1.2.4
