fix(cli): localize plugin/help command strings via i18n (closes #118) (#134)

Wire plugin module + help command + OAuth client-id/secret flags through
the existing i18n catalog so --help is consistent Chinese under zh locale
and English under en locale, instead of mixing the two.

- internal/app/plugin_cmd.go: wrap 16 Short strings with i18n.T
- internal/app/flags.go: wrap --client-id/--client-secret descriptions
- internal/app/root_help.go: override cobra default help command with a
  localized one so "dws help --help" and the utility-commands listing
  share the same catalog
- internal/i18n/locales/{en,zh}.json: add 20 new catalog entries

Verified under DWS_LANG=zh (all Chinese), DWS_LANG=en (original English
preserved), and LANG-based auto-routing. go test ./internal/app/... pass.

+## 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 -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.

+
+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 -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。
