将俄语 (ru) 纳入内置界面语言 (ship Russian as a built-in locale)

[warment]

一句话说明预期结果：Web UI 的语言选择器在 zh / en 之外提供「Русский」（俄语），与内置语言一样随内核发布。

验收与细节

• 验收条件：Settings → General 出现 Русский；所有内置命名空间字典包含 ru；fallback 链 ru → en 保持不变。
• 用户可见变化：俄语用户无需第三方插件即可切换界面语言；权限预设显示名等机器名也可通过同一机制本地化。
• 测试证据：社区语言包 deepseek-harness-locale-ru 已完成 33 个 namespace / 1061 个键（100% 覆盖），CI 校验对 upstream cd5ef81 通过；一条命令即可安装验证：dsh plugin --profile web add github:warment/deepseek-harness-locale-ru。

English summary. Proposal: ship Russian as a third built-in UI locale alongside zh/en. A complete, CI-verified corpus (33 namespaces, 1061 keys, formal register, unified glossary) already exists in the community pack deepseek-harness-locale-ru and can be contributed upstream as a reviewed PR series (locale definition first, then per-package dictionaries). Two additional options if core bundling is out of scope: (a) a docs link to community locale packs, and (b) a small refactor — moving slash-command descriptions and command settlement texts (currently source constants in host packages such as plan-mode, compaction, feedback, goal, session-log-export) into the client locale registries, which would let any locale pack translate them.

这个提案的验收条件已经比“翻译文件存在”完整很多。为了让外部语言包走向内置 locale 时仍可回归，建议把以下内容写成可重复的 release gate：

• 从 upstream 固定 revision 导出 namespace/key 清单，比较 ru 与 en 的缺失、额外和参数占位符差异；
• 对带插值、复数、Markdown、快捷键和错误码的字符串做参数形状检查，避免“100% key 覆盖”仍在运行时破坏格式化；
• 分别验证 Web UI、slash command、权限/审批、Session 恢复和空状态，而不是只验证 Settings 选择器；
• 明确 fallback 的可观察证据，并把外部插件安装、内置打包、升级回滚作为三条不同路径；
• 翻译内容本身不代表插件安全，外部 pack 仍应经过来源、依赖、bundle 权限和回滚审计。

独立社区手册维护了多语言入口和社区插件审计说明：https://github.com/sandbaseai/deepseek-harness-handbook/blob/main/docs/en/security/community-plugin-audit.md 。它不是 DeepSeek AI 官方项目；建议在最终 PR 中继续标注 upstream revision 与验证日期。

谢谢！这些 release gate 建议基本都已实现或已规划：

• 键清单 vs pinned revision：scripts/extract.mjs 从固定 upstream 检出导出 namespace/key 清单，check.mjs --strict 比较 ru 与 en 的缺失、额外键和双向 {placeholder} 差异（当前 1061/1061，对 cd5ef81）。
• 复数/插值：已发现并修复一类真实缺陷（客户端按 count === 1 二元处理复数，2–4 数字下格语法错误）——计数串统一改为无 согласование 形式（«Шагов: {count}»）。
• 回归路径三分（外部安装 / 内置打包 / 升级回滚）：外部路径已有干净环境安装+卸载测试；内置打包即本提案；升级回滚流程写入 docs/publish.md。
• 翻译 ≠ 安全：同意，SAFETY.md 已声明非官方产品并建议来源检查，会补充依赖与回滚审计要点。

若内核采纳内置 ru，社区字典可直接按包拆分贡献，验收门槛以上述 gate 为准。

(EN: most gates already implemented — pinned-revision key manifest with bidirectional placeholder checks in CI, a real plural-agreement defect class found and fixed, clean-room install/rollback tests for the external path. If core bundling is accepted, the community dictionaries can be contributed per-package against these gates.)

I support adding Russian as a built-in language in the Harness UI, available out of the box without installing a third-party plugin. Please include Russian translations for menus, buttons, settings, and user-facing messages, while keeping English available.

Please also add an “Auto” language option that selects the UI language based on the browser’s preferred language in the Web UI or the operating system’s language in the desktop app. For Russian browser/system locales (including ru-RU), it should automatically use Russian. Users should still be able to choose a language manually in Settings, with English as the fallback when a translation is unavailable.

Thank you for considering this!

Related proposal, may matter for how this one ships: make the UI locale an ordered preference list (e.g. ru → en → zh) instead of a single choice, so a partly translated UI falls back to a language the user actually reads rather than to untranslated islands and Chinese source keys. It also keeps the shipped-locale set from being a closed enum.
