Reduce MCP discovery timeouts

When MCP plugins are unreachable, the discovery times out too slowly and blocks commands. Reduced the overall discovery timeout from 10s to 4s and per-server timeout from 5s to 2s. Made the per-server timeout configurable.

+## Upgrade
+
+> Requires **v1.0.7** or later. For earlier versions, please re-run the [install script](#installation) to upgrade.
+
+dws has built-in self-upgrade capability. Updates are pulled directly from [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases) with SHA256 integrity verification and automatic backup.
+
+```bash
+dws upgrade                    # interactive upgrade to latest version
+dws upgrade --check            # check for new versions without installing
+dws upgrade --list             # list all available versions
+dws upgrade --version v1.0.7   # upgrade to a specific version
+dws upgrade --rollback         # rollback to the previous version
+dws upgrade -y                 # skip confirmation prompt
+```
+
+<details>
+<summary><strong>How it works</strong></summary>
+
+The upgrade process follows a two-phase atomic flow to ensure consistency:
+
+1. **Prepare** — downloads the platform-specific binary and skill packages to a temporary directory, verifies SHA256 checksums, and extracts/validates all files. If any step fails, the upgrade aborts without modifying the existing installation.
+2. **Apply** — only after all preparations succeed, the binary is replaced and skill packages are installed to all detected agent directories (`~/.agents/skills/dws`, `~/.claude/skills/dws`, `~/.cursor/skills/dws`, etc.).
+
+A backup of the current version is automatically created before each upgrade. Use `dws upgrade --rollback` to restore the previous version if needed.
+
+| Flag | Description |
+|------|-------------|
+| `--check` | Check for updates without installing |
+| `--list` | List all available versions with changelogs |
+| `--version` | Upgrade to a specific version (e.g. `v1.0.7`) |
+| `--rollback` | Rollback to the previous backed-up version |
+| `--force` | Force reinstall even if already on the latest version |
+| `--skip-skills` | Skip skill package update |
+| `-y` | Skip confirmation prompt |

 ## Getting Started

-### Step 1: Create a DingTalk Application
-
-Go to the [Open Platform Console](https://open-dev.dingtalk.com/fe/app?hash=%23%2Fcorp%2Fapp#/corp/app). Under "Internal Enterprise Apps - DingTalk Apps", click **Create App**.

-</p>
-</details>
-
-### Step 2: Configure Redirect URL
-
-Go to app settings → **Security Settings**. Add the following redirect URLs and save:
-
-```
-http://127.0.0.1,https://login.dingtalk.com
+```bash
+dws auth login            # browser opens automatically
+dws auth login --device   # for headless environments (Docker, SSH, CI)
 ```

-> `http://127.0.0.1` is for local browser login; `https://login.dingtalk.com` is for `--device` device-flow login (Docker containers, remote servers, and other headless environments). We recommend configuring both.
+Select your organization and authorize. That's it.
+
+> If your organization hasn't enabled CLI access, you'll be prompted to send an access request to your admin. Once approved, re-run `dws auth login`.

+3. Publish the app
+4. Login:

 ```bash
 dws auth login --client-id <your-app-key> --client-secret <your-app-secret>
 ```

-Or via environment variables:
-

-`client-id` and `client-secret` support multiple configuration methods with the following priority (highest to lowest):
-
-| Priority | Method | Description |
-|----------|--------|-------------|
-| 1 | CLI flags / Persisted config | `--client-id` / `--client-secret` command-line arguments; auto-saved after first successful login with `client-secret` stored in system Keychain |
-| 2 | Environment variables | `DWS_CLIENT_ID` / `DWS_CLIENT_SECRET` |
-| 3 | Default values | Hardcoded defaults (for development only) |
-
-**Recommended usage**:
- **First login**: Use `--client-id` and `--client-secret` flags; credentials are securely persisted after successful login
- **Subsequent use**: Run `dws` commands directly; token refresh automatically reads saved credentials from Keychain
- **CI/CD environments**: Use environment variables
+Credentials are securely persisted after first login (Keychain). Subsequent runs auto-refresh tokens.

+## 升级
+
+> 需要 **v1.0.7** 及以上版本。更早版本请重新执行[安装脚本](#安装)进行升级。
+
+dws 内置自升级能力，直接从 [GitHub Releases](https://github.com/DingTalk-Real-AI/dingtalk-workspace-cli/releases) 拉取更新，支持 SHA256 完整性校验和自动备份。
+
+```bash
+dws upgrade                    # 交互式升级到最新版本
+dws upgrade --check            # 仅检查是否有新版本
+dws upgrade --list             # 列出所有可用版本
+dws upgrade --version v1.0.7   # 升级到指定版本
+dws upgrade --rollback         # 回滚到上一版本
+dws upgrade -y                 # 跳过确认直接升级
+```
+
+<details>
+<summary><strong>工作原理</strong></summary>
+
+升级过程采用两阶段原子流程，确保一致性：
+
+1. **准备阶段** — 将平台对应的二进制文件和技能包下载到临时目录，校验 SHA256 校验和，解压并验证所有文件。任何步骤失败则立即中止，不会修改现有安装。
+2. **执行阶段** — 仅在所有准备工作成功后，替换二进制文件并将技能包安装到所有已检测到的 Agent 目录（`~/.agents/skills/dws`、`~/.claude/skills/dws`、`~/.cursor/skills/dws` 等）。
+
+每次升级前自动备份当前版本，可通过 `dws upgrade --rollback` 随时回滚。
+
+| Flag | 说明 |
+|------|------|
+| `--check` | 仅检查更新，不安装 |
+| `--list` | 列出所有可用版本及更新日志 |
+| `--version` | 升级到指定版本（如 `v1.0.7`） |
+| `--rollback` | 回滚到上一个备份版本 |
+| `--force` | 强制重新安装，即使已是最新版本 |
+| `--skip-skills` | 跳过技能包更新 |
+| `-y` | 跳过确认提示 |

 ## 开始使用

-### 步骤 1：创建钉钉应用
-
-进入 [开放平台应用开发后台](https://open-dev.dingtalk.com/fe/app?hash=%23%2Fcorp%2Fapp#/corp/app)，在「企业内部应用 - 钉钉应用」点击**创建应用**。
-

-</p>
-</details>
-
-### 步骤 2：配置重定向 URL
-
-进入应用 → **安全设置**，在「重定向 URL」中添加以下地址并保存：
-
-```
-http://127.0.0.1,https://login.dingtalk.com
+```bash
+dws auth login            # 自动唤起浏览器
+dws auth login --device   # 无浏览器环境（Docker、SSH、CI）
 ```

-> `http://127.0.0.1` 用于本地浏览器登录；`https://login.dingtalk.com` 用于 `--device` 设备流登录（Docker 容器、远程服务器等无浏览器环境）。建议两个都配置。
+选择组织并授权即可。
+
+> 如果组织尚未开启 CLI 访问权限，系统会引导你向管理员发送申请。审批通过后重新执行 `dws auth login` 即可。

 <details>
-<summary>查看截图</summary>
+<summary><strong>组织未开启 CLI 访问权限？</strong></summary>
+
+1. 选择组织后，点击「立即申请」通知管理员
+2. 管理员收到申请卡片，一键审批
+3. 审批通过后，重新执行 `dws auth login`

-
-点击「应用发布 - 版本管理与发布」，发布版本使应用上线。
-

-### 步骤 4：申请白名单
+<details>
+<summary><strong>自建应用模式（CI/CD、ISV 集成）</strong></summary>

-加入钉钉 DWS 共创群，提供 **Client ID** 和**管理员确认凭证**完成白名单配置。
+企业自主管控场景，可创建自有钉钉应用：

-### 步骤 5：登录认证
+1. [开放平台应用开发后台](https://open-dev.dingtalk.com/fe/app#/corp/app) → 创建应用
+2. 安全设置 → 添加重定向 URL：`http://127.0.0.1,https://login.dingtalk.com`
+3. 发布应用
+4. 登录：

 ```bash
 dws auth login --client-id <your-app-key> --client-secret <your-app-secret>
 ```

-或通过环境变量：
-
-```bash
-export DWS_CLIENT_ID=<your-app-key>
-export DWS_CLIENT_SECRET=<your-app-secret>
-dws auth login
-```
-
-<details>
-<summary><strong>凭证配置优先级</strong></summary>
-
-`client-id` 和 `client-secret` 支持多种配置方式，按以下优先级生效（从高到低）：
-
-| 优先级 | 配置方式 | 说明 |
-|------|----------|------|
-| 1 | CLI 参数 / 持久化配置 | `--client-id` / `--client-secret` 命令行参数；首次登录成功后自动保存，`client-secret` 存储在系统 Keychain 中 |
-| 2 | 环境变量 | `DWS_CLIENT_ID` / `DWS_CLIENT_SECRET` |
-| 3 | 默认值 | 代码中的预设值（仅开发时使用） |
-
-**推荐用法**：
- **首次登录**：使用 `--client-id` 和 `--client-secret` 参数，登录成功后凭证会自动安全存储
- **后续使用**：直接运行 `dws` 命令，Token 自动刷新时会从 Keychain 读取已保存的凭证
- **CI/CD 环境**：建议使用环境变量配置
+首次登录后凭证安全存储（Keychain），后续自动刷新 Token。
