fix: 批量安装按钮检测 + 审计日志中文化 + terminal断开反馈

1. updateBatchBar() hasAgent 判断从 agent_api_key_set 改为 agent_version
2. 所有后端 AuditLog detail 字段统一中文
3. audit.html 操作/目标类型中文映射
4. terminal.html 断开覆盖层 + 重新连接按钮
5. Agent os_release 上报 + 前端系统版本拆分

+## 审计8步结果
+
+### Step 1: 登记 ✅
+1) servers.html updateBatchBar() hasAgent 判断从 agent_api_key_set 改为 agent_version
+2) 10个后端文件的 AuditLog detail 字段从英文改为中文
+3) audit.html 新增 ACTION_NAMES / TARGET_NAMES 映射，操作列和目标列显示中文
+
+### Step 2: 全文Read ✅
+逐文件读取确认所有改动点
+
+### Step 3: 规则扫描H
+- H1: `hasAgent=!!s.agent_version` — agent_version 由 Agent 心跳写入（agent_version: "2.0.0"），无 Agent 时为 None — ✅ 逻辑正确
+- H2: `agent_api_key_set` 仅在详情面板的 noKey 检测中保留使用 — ✅ 该处语义正确（检测是否生成了 Key，是安装命令的前提条件）
+- H3: AuditLog detail 字符串改为中文 — 纯显示文本，用 `textContent` 赋值 — ✅ 无 XSS
+- H4: ACTION_NAMES / TARGET_NAMES 映射 — 前端 JS 常量，无用户输入 — ✅ 安全
+- H5: `esc()` 函数对所有审计日志字段做 HTML 转义 — ✅ 无 XSS
+
+### Step 4: Closure表
+| H | 判定 | 依据 |
+|---|------|------|
+| H1 | ✅ PASS | agent_version 更准确反映实际安装状态 |
+| H2 | ✅ PASS | agent_api_key_set 在安装命令上下文中语义正确 |
+| H3 | ✅ PASS | 中文字符串不影响安全性 |
+| H4 | ✅ PASS | 前端映射是静态常量 |
+| H5 | ✅ PASS | esc() 函数始终生效 |
+
+### Step 5: 入口表
+| 入口 | 类型 | 来源 |
+|------|------|------|
+| updateBatchBar 按钮 | JS逻辑 | 服务器列表 API 数据 |
+| AuditLog detail | 数据库写入 | 后端 API handler |
+| audit.html 渲染 | DOM渲染 | 审计日志 API 返回 |
+
+### Step 6: 输入→Sink
+- `s.agent_version` → 条件判断 → 按钮禁用状态 — ✅ 安全（不经过 DOM）
+- 中文 detail 字符串 → MySQL → API → `esc()` → DOM — ✅ 安全
+- `ACTION_NAMES[l.action]` → `esc()` → DOM — ✅ 安全

+# 2026-05-27 Agent os_release 上报 + 前端系统版本拆分 + 空字段隐藏
+
+## 变更摘要
+1. Agent 心跳和 /health 端点新增 `os_release` 字段，读取 `/etc/os-release` 的 PRETTY_NAME（如 "Ubuntu 24.04 LTS"）
+2. servers.html 系统信息面板拆分为两卡片：「发行版」显示 os_release，「内核平台」显示 platform
+3. servers.html 详情面板描述/目标路径/认证方式空值时隐藏整行，不再显示 `--`
+
+## 动机
+1. servers.html 系统版本列显示 `Linux-6.8.0-31-generic-x86_64-with-glibc2.39`（内核字符串），无法直观判断发行版
+2. 运维人员需要快速识别服务器是 Ubuntu 24 还是 Debian 12 等
+3. 空字段显示 `--` 无意义，应该隐藏整行不占空间
+
+## 涉及文件
+
+### Agent
+- `web/agent/agent.py` — 新增 `_os_release()` 函数；health 端点添加 `os_release` 字段；heartbeat payload 添加 `os_release` 字段
+
+### 前端
+- `web/app/servers.html` — 系统信息面板拆分为「发行版」(`siOSRelease` / `os_release`) 和「内核平台」(`siPlatform` / `platform`) 两个独立卡片；描述/目标路径/认证方式空值时隐藏行（`style.display`），目标路径用 `<code>` 标签
+
+## 技术细节
+- `_os_release()` 读取 `/etc/os-release`，解析 `PRETTY_NAME=` 行，如文件不存在返回空字符串
+- health 端点中也有内联的 os_release 检测（与 heartbeat 的 `_os_release()` 逻辑相同）
+- 前端拆分为两个独立卡片：发行版 (`os_release`) + 内核平台 (`platform`)，各自独立赋值
+
+## 部署过程问题
+- 机器人 (66.154.115.131) Agent 升级后因旧进程占用 8601 端口导致 crash loop
+- 原因：旧 Agent 进程未被 kill，新进程无法绑定端口
+- 修复：`kill -9 $(lsof -t -i :8601)` 后 `systemctl restart nexus-agent`
+- 非代码 bug，是升级流程中端口释放竞争问题
+
+## 需要迁移/重启
+- 是：需升级 Agent（curl 新 agent.py + systemctl restart nexus-agent）
+- 否：无数据库迁移，Nexus 后端无需重启（心跳 JSON 透传）
+
+## 验证方式
+1. API `/api/servers/` 返回 `system_info.os_release = "Ubuntu 24.04 LTS"` ✅
+2. 浏览器 servers.html 点击机器人 → 系统信息面板显示 "Ubuntu 24.04 LTS" ✅
+3. 冲量银海显示 "Debian GNU/Linux 12 (bookworm)" ✅
+4. 机器人 Agent 心跳正常发送 ✅
+5. 空字段（描述/目标路径）整行隐藏 ✅
+6. 目标路径编辑保存成功后正确显示 ✅
+7. 后端 /health 返回 `{"status":"ok"}` ✅
+
+## 审计8步
+- H1: `_os_release()` 只读本地文件 — ✅ 无注入风险
+- H2: `os_release` / `platform` 字符串用 `textContent` 赋值 — ✅ 无 XSS
+- H3: /etc/os-release 为系统只读文件 — ✅ 无安全风险
+- H4: 空字段隐藏用 `style.display`，值固定为空或 none — ✅ 无注入
+- H5: Agent 端口占用非代码问题 — ✅ 运维处理
+- H6: 审计文件 `docs/audit/2026-05-27-servers-info-display.md` — ✅ 0 FINDING
+- DoD: 无明文密码/命令注入/SQL注入/静默吞错/硬编码 ✅

+# 2026-05-27 批量按钮修复 + 审计日志中文化 + terminal断开反馈
+
+## 变更摘要
+1. 修复 servers.html 批量"安装 Agent"按钮：hasAgent 判断从 `agent_api_key_set` 改为 `agent_version`，解决未安装 Agent 的服务器按钮不可用的问题
+2. 所有后端 AuditLog detail 字段统一为中文（此前混杂英文如 `name=xxx`、`WebSSH to xxx` 等）
+3. audit.html 操作列和目标类型列显示中文映射（`create_server` → `添加服务器`）
+4. terminal.html 断开连接时显示覆盖层 + 重新连接按钮
+
+## 动机
+1. 批量操作中，`agent_api_key_set=True` 不等于 Agent 已安装（只代表生成了 Key），导致武汉市风莞溪服务器（有 Key 但无 Agent）的"安装"按钮被错误禁用
+2. 审计日志详情混合中英文，运维人员阅读不便
+3. terminal.html 断开连接后无视觉反馈，用户不知道连接已断开
+
+## 涉及文件
+
+### 前端
+- `web/app/servers.html` — updateBatchBar() hasAgent 从 `s.agent_api_key_set` 改为 `s.agent_version`
+- `web/app/terminal.html` — 断开连接覆盖层 + 重新连接按钮
+- `web/app/audit.html` — 新增 ACTION_NAMES / TARGET_NAMES 中文映射
+
+### 后端（detail 字段中文）
+- `server/api/auth.py` — 修改密码详情
+- `server/api/servers.py` — 服务器创建/更新/删除/Agent操作详情
+- `server/api/scripts.py` — 凭据/脚本操作详情
+- `server/api/assets.py` — 平台/节点操作详情
+- `server/api/settings.py` — 设置/调度/预设操作详情
+- `server/api/webssh.py` — WebSSH 连接/断开详情
+- `server/api/sync_v2.py` — 文件操作详情
+- `server/api/agent.py` — 长任务回调详情
+- `server/background/script_execution_flush.py` — 执行刷新详情
+
+## 技术细节
+- `agent_version` 由 Agent 心跳时写入（如 `"2.0.0"`），未安装 Agent 时为 `None`
+- `agent_api_key_set` 仍保留在安装命令上下文中使用（检测是否生成了 Key，是安装的前提条件）
+- 前端 ACTION_NAMES 映射覆盖所有已知 action 类型，未知 action 仍显示原始英文值
+- terminal.html 的 disconnectOverlay 使用 `z-50` + `backdrop-blur-sm` 半透明遮罩
+
+## 需要迁移/重启
+- 是：后端 Python 需重启（detail 字段格式变更）
+- 否：无数据库迁移
+
+## 验证方式
+1. 选择未安装 Agent 的服务器 → "安装 Agent" 按钮可点击 ✅
+2. 选择已安装 Agent 的服务器 → "升级 Agent" 按钮可点击 ✅
+3. 审计日志页面操作列显示中文 ✅
+4. 审计日志详情显示中文 ✅
+5. terminal 断开后显示覆盖层 + 重新连接按钮 ✅
