=== 一、主机「测试连接」永远显示旧错误（真实 bug）===
HostService.Validate 的失败分支也写 status=active，且从不写 statusMessage：
if info, err := client.GetHostInfo(ctx); err == nil { 更新 os/arch }
else { s.Update(id, {status:"active"}) } // ← 失败也标记成功
结果：连不上也显示正常，页面永远停在几分钟前的旧错误文案，
用户改了 IP 再点测试，还以为"改了还是不行"。
改为区分成功/失败并写清原因：
成功 → status=active + os/arch + statusMessage="连接成功"
失败 → status=error + statusMessage=FormatSSHError(err)
=== 二、回环地址在平台里必然连不上 ===
平台跑在容器/Pod 内，127.0.0.1 指向平台自身。
- 新建主机时拦截：hostIP 为 127.0.0.1/localhost/::1 直接报错并解释原因
- 前端表单同步校验 + 文案
- SSH 错误映射补充：连接被拒绝时提示可能是地址填了回环
=== 三、主机模式采集系统日志（两处会导致采集失败）===
1. pipeline 一律套 cri 阶段：cri 只认容器运行时格式，
套在 /var/log/messages 这类 syslog 上会取不到时间戳、整行被丢。
→ appPipelineStages() 按路径判断：容器日志用 cri，普通文本日志只做限流。
2. promtailExternalLabels 写死 8 空格缩进：主机模板 external_labels 只有 4 空格，
一旦给采集器配置了标签就生成非法 YAML，Promtail 装不上。
→ 增加 indent 参数，主机 6 空格 / DaemonSet 8 空格。
3. 新增 system 采集任务：
/var/log/{messages,secure,cron,maillog,syslog,dmesg}
正则解析 syslog 时间戳（Jan _2 15:04:05，Asia/Shanghai）+ 限流
测试：TestHostPromtailConfigValid / CRIPathKeepsCRIStage / PlainFileHasNoCRIStage
TestPromtailManifestParses 全部通过
=== 四、资源用量 CPU 解析（nanocores）===
metrics-server 返回的 CPU 常是纳核（如 "194533645n"=194.5m）。
原解析只处理 "m"，导致 194 亿核、页面出现"CPU 已达 limit 的 4863341125%"。
→ parseQuantityMilli 支持 n/u/m/整核
实测：CPU 当前=178m，峰值=3300m，建议"峰值占 limit 82%，可考虑提前扩容"
=== 五、其他 ===
- 添加集群默认改用 Token 认证（最小权限、可随时吊销）
- RBAC 片段补 metrics.k8s.io（资源面板需要，独立 API 组常被漏授）
- 文案去掉 Grafana 需求描述（平台自身不部署 Grafana）
