Merge branch 'feature/chrome-i18n' into develop

迁移 i18n 系统从 react-i18next 到 chrome.i18n：
- 移除 react-i18next 依赖，使用 chrome.i18n API
- 生成 _locales/zh/messages.json（245 个翻译 key）
- 清理未使用的翻译 key
- 移除语言切换按钮和英文翻译

-i18next 初始化配置：
-
-- 同步加载 `common` 和 `features` 核心命名空间
-- 自定义 `chromeStorage` 语言检测器，从 Chrome Storage 读取语言偏好
-- `normalizeLanguage()` 将任意语言标识归一化为 `zh` 或 `en`
-- 语言变更时同步更新 Day.js 本地化和 localStorage 快照
-
-## 翻译键格式
-
-- 命名空间：`common`（默认）、`features`、各功能独立命名空间
-- 键格式：`namespace:key`（如 `features:timestamp.title`、`timestamp:unitMs`）
-
-## 使用方式
-
-```tsx
-// 页面组件 — 懒加载翻译
-import { useLazyTranslation } from '@/utils/useLazyTranslation';
-const { t } = useLazyTranslation('timestamp');
-t('timestamp:title');
-
-// 全局组件 — 直接使用
-import { useTranslation } from 'react-i18next';
-const { t } = useTranslation(['common', 'features']);
-t('common:settings');
-```
-
-## 添加新翻译
-
-1. 在 `locales/{zh,en}/features.json` 添加功能标题和描述
-2. 创建 `locales/{zh,en}/{功能名}.json` 添加功能专属翻译
-3. 在 `utils/useLazyTranslation.ts` 的 `localeModules` 中注册新命名空间
