chore(release): v1.5.0

## 背景
原 `input.key.press` 只接受数组和弦（keys/sequence），按键表也不全：
AI/MCP 调用要拼 ["ctrl","shift","esc"]，且 **win+d、ctrl++、win+. 这类
"修饰键 + OEM 符号键"的组合根本打不出来**（表里没有符号键）。

## 四类扩展
① **字符串热键**：`hotkey: "ctrl+shift+esc"`、`hotkeys: ["ctrl+c","ctrl+v"]`
   —— 分隔符支持 `+ - 空格`，大小写不敏感，别名归一（command/cmd→win、del→delete…）
② **预设别名**：约 50 个语义名（copy / show_desktop / task_manager / screenshot /
   volume_mute_toggle…），AI 调用免记键位；`preset` 与 `presets`（序列）均支持
③ **长按** `hold_ms`（≤5s）：按下→保持→释放，插在"按完"与"释放"之间
④ **后台定向投递** `route=post` + `target_pid`：向目标进程**全部顶层窗口**
   PostMessage WM_KEYDOWN/UP —— 目标窗口被遮挡/最小化时可用
   （媒体键的 WM_APPCOMMAND 机制早已验证，此为其等价物）
   文档明示局限：游戏/部分输入型程序不响应后台键消息

## 按键表补齐（单测覆盖断言防漂移）
- 左右侧修饰键 lctrl/rctrl/lshift/rshift/lalt/ralt/lwin/rwin（游戏常区分左右）
- 小键盘 numpad0-9 + 四则运算，**与数字键分开**（Excel 靠 NumLock 区分）
- OEM 符号键 oem_1..oem_8 / oem_minus/plus/comma/period（解锁 win+d、ctrl++、win+.）
- 浏览器收藏夹/主页、系统键（sleep/help/select/execute/clear/separator/oem_clear）
- IME 键（kana/hangul/kanji/hanja/convert/nonconvert/accept/modechange）
- 补齐 pause/apps（重构时一度漏掉，被覆盖断言测试立刻抓到）

## 可测性重构
脚本生成抽成**纯函数** `apps/agent/src/capabilities/input-script.ts`
（VK_MAP / MEDIA_COMMANDS / toVk / build{Media,Foreground,Post}Body），
行内生成逻辑全部改为调用 —— 于是**按下顺序/逆序释放/hold 插入位置/post 路由**
这些最容易写错的部分，现在由 14 个单测逐行断言，真机只需验证最终效果。

## 参数校验
protocol `expandChords()` 统一展开六种输入形式，**混用即报错**（消除"以谁为准"歧义）；
同一和弦重复修饰键、超 4 键、空输入均拒绝。渲染返回值新增 presets/via/channel/sent_windows。

## CLI / MCP
- CLI：`nodeagent key press "ctrl+shift+esc"` / `key press copy` / 老形式 `key press ctrl c`
  新增 `--hold`、`--route`；回显预设展开与后台投递命中窗口数
- MCP `na_key`：同步支持 hotkey/hotkeys/preset/presets/hold_ms/route/target_pid

## 验证
- 单测 **179 → 195**：hotkeys 解析与别名 17 例、**脚本生成逐行断言 14 例**、
  按键覆盖断言（HOTKEY_KEYS ⊆ VK_MAP）、新参数 schema 校验 2 例
- e2e **29** 全绿
- ⚠️ **真机未验证**：Windows 被控端当前离线（连接超时）。待上线后需验：
  `key press "win+d"`（切桌面再切回）、`key press copy` 配剪贴板、
  `route=post` 定向一个最小化窗口。验证通过后再发版。

+ * 音频控制（v17）：静音开关与主音量。
+ *
+ * ## 为什么需要
+ * 远程接管一台机器时，「把它静音」是高频且刚需的小事（夜里吵、放视频要音量、
+ * 排障时确认音频设备）。此前只能靠 exec 拼一段脚本，容易踩本项目已记录的
+ * 各种坑（C# 转义 / 编码 / 引号），故做成正式能力。
+ *
+ * ## 平台实现
+ * - Windows：**Core Audio COM**（IMMDeviceEnumerator → IAudioEndpointVolume）
+ *   —— 可**读回真实状态**，因此是确定性的「设为静音」而非「切换」
+ *   （切换在状态未知时可能反而打开声音）。不用 Add-Type -AssemblyName 那套，
+ *   是因为音量不在 .NET BCL 里，只能用 COM 互操作。
+ * - macOS：`osascript` 的 volume 设置（原生，无需互操作）。
+ *
+ * ## C# 互操作的两个硬约束（本项目踩过的坑，勿改）
+ * 1. **槽位顺序即 vtable 顺序**：接口方法必须按 COM 定义顺序声明，
+ *    不调用的方法也要占位（占位方法签名无所谓，但不能漏）。
+ *    顺序错了不会编译报错，而是调用到错误的内存地址 → 进程崩溃。
+ * 2. **C# 源码必须纯 ASCII**：Add-Type 按系统 ANSI(GBK) 落盘，非 ASCII 会乱码。

+ *    没有它，GitHub 账号被盗 / DNS 被污染 / 中间人 = 直接拿下被控端。
+ * 2. 只接受 http/https；拒绝 file:// 等其它 scheme。
+ * 3. 大小上限（默认 64MB）+ 下载超时，避免被喂垃圾撑爆磁盘。
+ * 4. **先备份再原子替换**（同目录 rename），失败可回滚。
+ * 5. `dry_run` 只下载校验、不动现有文件 —— 用于「先确认能不能更新」。
+ * 6. 动作全程进审计（能力调用本身已记录 `invoke`，这里再加一条 `agent.update`）。

+ * Node 内置 `fetch` 不支持 HTTP 代理（需要 undici 的 ProxyAgent，而 undici 未对外暴露）。

+ * 而脚本开头是 `Add-Type @"..."@`（**现编译 C#**）+ `Add-Type -AssemblyName UIAutomationClient`。
+ * 真机实测（agent 侧中位）：window.list **1267ms**、window.focus **1631ms** —— 大头就是
+ * 「起进程 + 编译类型」这一次性开销，与每次任务的复杂度无关。
+ *
+ * ## 做法
+ * 起一个**常驻** PowerShell 进程：启动时把 prelude（C# 类型 / UIA / WinRT 程序集）
+ * 全部加载一次，之后每个请求只发「本次逻辑」（base64 一行），进程内直接执行并回传结果。
+ * 进程内还有 UIA 的元数据缓存收益。
+ *
+ * ## 不变量（工程纪律）
+ * - **可用性不倒退**：助手不可用/超时/连续失败 → 自动回退到原有「一次性脚本」路径，
+ *   且熔断后本进程不再重试助手（避免每次调用都白等一次超时）。
+ * - **不泄漏**：空闲 10 分钟自动退出；agent 关闭时统一回收。
+ * - **可观测**：暴露 stats（调用次数/命中率/最近错误）供诊断。

+
+## 杀软误拦（主流杀软 / 杀软 / 360）
+
+**现象**：远程接管类工具的典型特征（未知 exe + 建计划任务 + 开防火墙 + 常驻监听 + 注入键鼠/截屏）
+**必然**触发杀软拦截。真机实证：主流杀软会拦下 `install.ps1` 执行、计划任务注册，或直接处置 `node.exe`，
+表现为「下载成功但装不上」或「装上后 agent 起不来」。
+
+**逐项放行清单**（把下面这些都加进杀软的信任/白名单，而不是整机关防护）：
+
+| 对象 | 说明 |
+|---|---|
+| 安装目录 | 解压出来的整个文件夹（含 `node.exe`、`agent.mjs`、`install.ps1`） |
+| `node.exe` | 被控端自带的 Node 运行时（免装 Node 就是因为这个文件） |
+| `agent.mjs` | agent 主体（常驻监听 8765） |
+| 计划任务 `nodeagent` | 开机/登录自启任务；主流杀软的「启动项拦截」会静默拦掉它 |
+| 入站端口 8765/TCP | `install.ps1` 已建防火墙规则；杀软的**独立网络防护**可能仍拦 |
+| PowerShell 脚本执行 | 主流杀软「系统加固」会拦脚本解释执行；至少放行上面的安装目录 |
+| 键鼠/截屏行为 | 开启 `allow_input` 后才会出现；若被拦，`screen.capture`/`input.*` 会失败 |
+
+**自检命令**（在 Windows 上跑，确认三件事：任务在不在、进程活不活、端口听没听）：
+```powershell
+Get-ScheduledTask -TaskName 'nodeagent*' -ErrorAction SilentlyContinue | Select-Object TaskName, State
+Get-Process node -ErrorAction SilentlyContinue | Select-Object Id, Path

+Invoke-WebRequest 'http://127.0.0.1:8765' -UseBasicParsing -TimeoutSec 2   # 有响应即端口通
+```
+
+**排查顺序**：先看任务与进程（被杀软处置则两者都缺）→ 再看端口（进程在但端口不通 = 防火墙/杀软网络防护）
+→ 最后从控制端用 `nodeagent discover` 或 ping 确认**两台机器确实在同一网络**。
+
+> ⚠️ 最后一环最容易忽略：真机踩过 —— 控制端换了 Wi-Fi（酒店/热点）后仍在扫旧网段，
+> 排查半天「失联」，实际是**两台机器不在同一网络**。先用 `ipconfig`/`ifconfig` 对齐网段再谈其他。

+# 安全模型与加固指南
+
+> 面向使用者与运维者。协议细节见 `DEVELOPMENT.md`，发版与升级见 `VERSIONING.md`。
+
+## 1. 信任模型：钥匙 = 那台机器的 root
+
+`system.shell.exec` 能执行任意命令，所以**拿到预共享密钥（PSK）就等于拿到被控端的 root**。
+请按 root 密码的标准保管它：不外传、不进版本库、不进公开安装包、不贴进聊天/工单。
+
+被控端首启时用 CSPRNG（`crypto.getRandomValues`，32 字节 / 256 bit）在本机生成密钥，
+只存在 `<数据目录>/agent.json`，**不进任何分发包**。
+
+## 2. 认证做了什么（已具备）
+
+| 机制 | 说明 |
+|---|---|
+| 挑战-应答 | `hello → challenge(nonce) → auth(HMAC / Ed25519 签名)`，**钥匙全程不上网** |
+| nonce 一次性 | 用后即废（`server.ts` 置 null），抓包重放无效 |
+| 协议主版本校验 | 不一致直接 `E_PROTOCOL_MISMATCH` 拒连 |
+| 能力级 ACL | `deny → allow → 默认拒绝`（**身份维度仅在 ed25519 模式有效**） |
+| 调用限速 | 按 client_id 滑动窗口 |
+| 审计链 | 每条含前一条哈希，可验篡改 |
+| 键鼠控制 | **默认禁用**，需显式开启 |
+
+> ⚠️ **PSK 模式的固有限制**：`client_id` 由客户端自报，ACL 的「身份」维度挡不住
+> 持有同一把钥匙的人伪装成任意 client_id。要真正按身份授权，请用 **ed25519**
+> （`nodeagent keygen` → 公钥登记到被控端 ACL → `--auth-mode ed25519`）。
+
+## 3. v21 加固一：证书指纹钉住（TOFU）
+
+自签证书没有 CA 链，历史上只能 `insecure` 接受任意证书 —— 于是同网段的中间人可以
+**透明中继**（拿不到钥匙，但能读到截屏/剪贴板/键入内容）。现在：
+
+1. 被控端在 `install.ps1` 输出里打印 **TLS 证书指纹**（sha256 of DER）
+2. 控制端**首次**连接时把它钉进 `~/.nodeagent/config.json`（`nodes.<名>.cert_sha256`）
+3. 之后每次连接**严格比对**，不一致直接拒绝：
+
+```
+✗ E_CERT_MISMATCH: 证书指纹不匹配，拒绝连接：期望 2ed4957b… 实际 ca8dc20c…
+   （被控端可能重装了、或中间人冒充）
+```
+
+**带外核对（重要）**：装机时屏幕/终端上会印一个 64 位指纹，与控制端首次连接打印的
+`🔐 已钉住被控端证书指纹` 比对 —— 不一致说明你连的不是那台机器。
+
+被控端**重装系统 / 证书重建**后指纹必然改变，此时显式重钉：
+
+```bash
+nodeagent connect <地址> --port 8765 --key <密钥> --insecure --forget-cert
+```
+
+查看当前状态：`nodeagent info`（会显示「已钉住 … 本次一致 ✓ / 未钉住」）
+
+## 4. v21 加固二：来源网段白名单（`allow_from`）
+
+被控端默认监听 `0.0.0.0`（为了能远程接入）。这意味着**机器一换网络就自动暴露** ——
+连到咖啡厅/酒店/便利店的 Wi-Fi 时，同网段任何人都能看到它的 8765 端口。
+
+在被控端 `agent.json` 里限制来源：
+
+```json
+{
+  "host": "0.0.0.0",
+  "port": 8765,
+  "allow_from": ["192.168.0.0/16", "10.0.0.0/8"]
+}
+```
+
+- 支持 CIDR、单 IP、以及 `*`（放行全部）
+- **未配置 = 放行全部**（保持向后兼容）；`nodeagent info` 会提示尚未收敛
+- 拒绝发生在**业务握手之前**（不浪费 TLS/挑战应答开销），并记 `net.deny` 审计
+- 判定按**前缀比特**而非字符串相等 —— Node 在 IPv6 监听上把 IPv4 客户端报成
+  `::ffff:a.b.c.d`，已做归一化
+
+## 4.5 发现广播最小化（v22）
+
+UDP 广播是**未认证**的：默认配置下同网段任何人都能看到
+「哪台机器可接管 / IP / 端口 / 用什么认证 / 键鼠是否开着」。
+
+```json
+"discovery": { "detail": "minimal", "secret": "<与控制端相同的密钥>" }
+```
+
+- `detail: "minimal"`：顶层只留 `service / version / node_id / ts`，
+  真实信息收进 `detail{}`（**同网段看不到地址、端口、认证方式、键鼠开关**）
+- 配了 `secret`：`detail` 带 **HMAC 签名**（`node_id|ts|JSON(detail)`），
+  控制端用同一密钥验签 → 列表里显示 **🔒 已认证**；没配/验签失败显示 **⚠️ 明文**（仅作参考）
+- 控制端：`nodeagent discover --discover-secret <同一密钥>`
+- 未配置时 agent 启动会打印醒目告警，提示收敛
+
+> 仍会暴露「这里有一台可被接管的机器」（存在性无法隐藏，除非关广播或改用 Hub）。
+> 真正的身份确认始终发生在**握手之后**（`auth_ok` 带证书指纹，控制端严格比对）。
+
+## 4.6 每客户端一把 PSK（v22，psk 模式下的身份绑定）
+
+psk 模式里 `client_id` 由客户端自报，所以**一把共享 key 意味着持有者可冒充任意 client_id**，
+ACL 的身份维度形同虚设。v22 起支持按 client_id 分配独立钥匙：
+
+```bash
+# 控制端：为某个 client_id 生成专属 PSK
+nodeagent keygen --psk --id mac_02
+```
+
+```json
+// 被控端 agent.json（可并列多个 client_id）
+{ "keys": { "mac_02": "<那把密钥>" } }
+```
+
+效果（已实测）：
+
+| 场景 | 结果 |
+|---|---|
+| alice 用自己的 key | ✅ 通过 |
+| **alice 的 key 冒用 bob 身份** | ❌ `E_AUTH_FAILED` |
+| bob 用自己的 key | ✅ 通过 |
+| 未登记的 client_id 用共享 `key` | ✅ 通过（**旧部署行为不变**） |
+| 已登记的 client_id 用共享 `key` | ❌ 拒绝（**专属钥匙优先**，不被共享 key 绕过） |
+
+## 5. 还没做的（后续批次）
+
+| 项 | 说明 |
+|---|---|
+| ~~发现报文最小化~~ | ✅ **v22 已做**（见 §4.5） |
+| ed25519 默认化 | 新装仍默认 psk；v22 提供了更轻量的替代：`keys{}` 每客户端一把 PSK（见 §4.6） |
+| 握手失败封禁 | 目前只计数 + 审计，无按 IP 的临时拉黑 |
+| 审计链签名 | 哈希链可被「有 root 的攻击者」整链重写，缺外部锚定 |
+| 会话上限 | 无最大连接数与空闲断开 |
+| 安装期密钥传递 | `install.cmd` 用命令行 `-Key` 传参，同机其他用户 `ps` 可见 |
+
+## 6. 应急处置
+
+| 场景 | 处置 |
+|---|---|

+# 版本与兼容性契约
+
+> 为什么需要这份文档：agent 与 CLI/MCP 是**分开更新的**（CLI 随控制端装，agent 推/拉到被控端），
+> 新旧混用是常态而非例外。没有明文契约，升级顺序、什么算破坏性改动、出问题怎么定位全靠猜。
+
+## 1. 版本号
+
+- 单一来源：**根 `package.json` 的 `version`**，构建时经 esbuild `--define` 注入 agent。
+- 运行时可通过 `system.info` 的 `build` 字段读到：`version` / `commit`（git sha）/ `built_at` /
+  `hash`（运行中脚本的 sha256 前 12 位 —— 部署校验用）。
+- 控制端在握手（`auth_ok`）即拿到被控端版本，`nodeagent info` 会显示：
+  ```
+  被控端版本 : v1.0.0 @ ef9ad97  构建 740d51953fd0
+  能力对齐   : 42 项，两端一致 ✓
+  ```
+
+## 2. 语义化版本的含义
+
+| 变更类型 | 版本位 | 例子 |
+|---|---|---|
+| **破坏性**：删除能力、给既有能力**新增必填参数**、改变既有能力的返回结构、修改认证/握手流程 | MAJOR | 删掉 `screen.find`；把 `fs.read` 的 `path` 改成必填 `remote_path` |
+| **新增**：新能力、既有能力的**可选**参数、新增返回字段、新增审计事件类型 | MINOR | 加 `system.audio.*`、给 `deploy` 加 `--check` |
+| **修复/内部**：bug 修复、性能、文档、不影响协议的重构 | PATCH | 修备份编码、拆分文件 |
+
+## 3. 兼容性契约（硬规则）
+
+1. **只增不改**：既有能力的**参数名与语义不得变更**；要改就新增能力（如 `screen.find` 与未来的
+   `screen.find2` 并存一代），旧能力至少在下一个 MAJOR 才移除。
+2. **不新增必填参数**：既有能力只能加**可选**参数 —— 否则旧控制端一调就 `E_PARAM_INVALID`。
+3. **返回结构只加不减**：新增字段必须可选，旧控制端忽略即可。
+4. **`auth_ok` 的字段只增不减**：v20 新增的 `agent_version`/`build`/`protocol` 均为可选，
+   旧控制端不认也不报错。
+5. **协议主版本**（`PROTOCOL_VERSION` 的主号）不一致时被控端直接拒绝连接并返回
+   `E_PROTOCOL_MISMATCH` —— 这是唯一的硬闸门，用于承载**无法兼容**的协议变更。
+6. **能力清单是唯一事实源**：控制端不比版本号，而是比**能力集合**
+   （`capabilityDiff`）—— 版本号可能相同而内容不同（本地 dev 构建），能力集合不会骗人。
+
+## 3.1 v21 新增字段（均为**可选**，向后兼容）
+
+| 位置 | 字段 | 含义 |
+|---|---|---|
+| 被控端 `agent.json` | `allow_from: string[]` | 来源网段白名单；**未配置 = 放行全部**（与旧行为一致） |
+| 被控端 `system.info` | `build.cert_sha256` / `network.allow_from` | 证书指纹与白名单状态（供控制端展示与巡检） |
+| 被控端 `auth_ok` | `build.cert_sha256` | 同上（握手期即可得） |
+| 控制端 `nodes.<名>` | `cert_sha256: string` | **钉住**的被控端证书指纹；不一致即 `E_CERT_MISMATCH` 拒连 |
+| 发现报文 | `cert_sha256` | 未认证广播，**仅作参考**，不可当身份凭据 |
+
+新增错误码：`E_CERT_MISMATCH (-32422)`、`E_NET_DENY` 类事件走审计 `net.deny`。
+
+## 4. 升级顺序建议
+
+**先升级被控端，再升级控制端**：
+
+| 组合 | 结果 |
+|---|---|
+| 新被控端 + 旧控制端 | ✅ 安全。被控端只做加法，旧控制端不认识的新能力会被忽略 |
+| 旧被控端 + 新控制端 | ⚠️ 可用，但新功能不可用。`nodeagent info` 会列出**远端缺少**的能力并提示升级 |
+
+> 若顺序反了也不会坏：控制端调用缺失能力时返回 `E_CAPABILITY_NOT_FOUND`，
+> 而 `nodeagent info` / `connect` 会提前把它变成一句人话提示。
+
+## 5. 更新方式（两条路，按可达性选）
+
+| 方式 | 命令 | 前提 |
+|---|---|---|
+| 推送式 | `pnpm update:win <设备名>` | 控制端↔被控端**可达**；自动打包含校验与指纹复核 |
+| **拉取式** | `nodeagent update --url <地址> --sha256 <哈希>` | **只要被控端能上网**（含 GitHub Release） |
+
+先预检再更新（不动任何文件）：
+
+```bash
+nodeagent --node win update --url <地址> --sha256 <哈希> --dry-run
+```
+
+`--sha256` 是**安全底线**：不校验哈希等于开放远程代码执行。
+
+## 6. 发版流程
+
+```bash
+pnpm release patch|minor|major|<x.y.z>   # 改版本 → 构建 → 打包 → 校验和/清单 → 提交打标签 → GitHub Release
+pnpm release 1.0.0 --dry-run             # 演练（无任何副作用）
+```
+
+产物（GitHub Release 资产）：
+
+| 资产 | 用途 |
+|---|---|
+| `agent.mjs` | **自更新载荷** —— 被控端 `system.agent.update` 直接用它（配 `--sha256`） |
+| `nodeagent-win-x64.zip` | 人工安装包（自包含 `node.exe`，免装 Node.js） |
+| `latest.json` | 版本清单：version/commit/built_at/capabilities + 两个资产的 url 与 sha256 |
+| `SHA256SUMS` | 校验和 |
+
+> ⚠️ **首次仍需一次性安装**：自更新能力本身得先在机器上（鸡生蛋无解）。
+> ⚠️ **`node.exe`（Node 运行时）不在自更新范围**：只换 `agent.mjs`；需升级 Node 时重跑 `install.ps1`。
+> ⚠️ 本仓库的 `.github/` 改动需要 `workflow` 权限才能推送（`gh auth refresh -h github.com -s workflow`），
+> 发版脚本刻意跳过 `.github/`，避免发版流程被它卡住。
+
+## 7. 出问题怎么排查
+
+```bash
+nodeagent --node win info                       # 版本 + 能力对齐情况（先看这个）
+nodeagent --node win invoke system.info --args '{"fields":["build"]}'   # 构建指纹
+nodeagent --node win deploy <包> --check        # 本地包 vs 远端是否一致（不改动）
+```
+
+- **远端过旧**：`info` 会列出缺失能力 → `nodeagent update ...`
+- **本控制端过旧**：`info` 会列出"不认识的新能力" → 更新控制端（`git pull` → `pack:mac` → `install-macos.sh`）
+- **同版本但指纹不同**：属正常（内容相同才叫同版本）；用 `--check` 对比实际内容
+- **部署后没生效**：先查杀软是否处置了被替换的 `agent.mjs`（见 `REMOTE-LIMITS.md` 的「杀软误拦」）

+ *   type     —— 输入文本
+ *   key      —— 按键/组合键/序列（keys 或 sequence，可 repeat）

+.SYNOPSIS

 .SYNOPSIS
     nodeagent - Windows agent installer.
 
+    ⚠️ 本文件必须以 **UTF-8 BOM** 保存（文件头那个看不见的 U+FEFF 就是 BOM）。
+       Windows PowerShell 5.1 读**无 BOM** 的 .ps1 会按系统 ANSI（中文 Windows = GBK）
+       解析，本文件里的中文注释会解成乱码并被误认为引号 → 整份脚本 ParseError
+       （报错位置彼此无关，真正的病灶在靠前处）。真机踩过：2026-10-04。
+       另：第 4 步写 agent.json 时反而必须**无 BOM**（BOM 对 .ps1 必需、对 JSON 有害）。
+
 .DESCRIPTION
     Registers the nodeagent agent as a scheduled task (auto-start on logon),
     opens the inbound firewall port, and prints connection info for the Mac side.

+.SYNOPSIS
+    nodeagent 网络救援脚本 —— 被控端因网络变更失联后的本地恢复。
+
+.DESCRIPTION
+    背景：`system.net.apply` 是两阶段提交（未确认自动回滚），但**如果回滚本身也失败**
+    （例如变更脚本把地址删掉了却没加上），机器可能落到 APIPA（169.254.x.x）而彻底失联。
+    这个脚本就是为那一天准备的：在**被控端本机**以管理员运行，把网络恢复到可用状态。
+
+    它做的事：
+      1. 列出所有网卡与当前地址（先看清现状）
+      2. 找出「有物理连接、但没有有效 IPv4」的网卡（典型的失联状态）
+      3. 把指定/自动识别的网卡设回给定静态地址，或切回 DHCP
+      4. 用**原生 NetTCPIP cmdlet** 按安全顺序执行：
+         先加地址 → 再清其它地址与残留默认路由 → 最后补默认路由
+         （顺序颠倒会踩 Windows 的「already exists」而再次失败 —— 真机事故根因）
+
+.PARAMETER Interface
+    网卡别名（如「Ethernet」）。省略则自动选取「已连接但无有效 IPv4」的那块。
+
+.PARAMETER Ip / PrefixLength / Gateway / Dns
+    要恢复的静态配置；省略 Ip 则切回 DHCP。
+
+.PARAMETER ListOnly
+    只看现状，不做任何变更。
+
+.EXAMPLE
+    # 先看现状
+    powershell -ExecutionPolicy Bypass -File rescue-network.ps1 -ListOnly
+
+.EXAMPLE
+    # 恢复为原静态地址（最常用）
+    powershell -ExecutionPolicy Bypass -File rescue-network.ps1 `
+        -Interface 'Ethernet' -Ip 192.168.1.100 -PrefixLength 24 -Gateway 192.168.0.1

+ *      所在位置 D:\Nodeagent\install.ps1:31 字符: 31
+ *      +     [string]$ProjectRoot = "",
+ *      “,”后面缺少表达式。
+ *    原因：5.1 读**无 BOM** 的 .ps1 会按系统 ANSI（中文 Windows = GBK）解码，
+ *    脚本里的中文注释/字符串被解成乱码，其中某些字节序列被误认成引号，
+ *    于是整份脚本的字符串边界全乱 —— 报出的一串语法错误彼此无关，
+ *    真正的病灶在文件靠前的位置。
+ *
+ *    **CI 之前全绿是因为冒烟步骤用 `shell: pwsh`（PowerShell 7，认无 BOM UTF-8）**，
+ *    只有真机的 5.1 会炸。故此用例 + CI 的 5.1 解析冒烟一起守。
+ *
+ * 对照：运行时**动态生成**的 .ps1 走 `apps/agent/src/capabilities/network.ts`
