feat: 增强多语言支持与本地化功能

- 新增多语言问题修复计划文档，详细描述了多语言支持的现状与解决方案。 - 在LocalizationManager中启用全局本地化方法，替换多个视图中的NSLocalizedString调用为LocalizedString。 - 更新MainFeature以确保在MeView标签页时正确加载用户数据。 - 在多个视图中添加语言切换测试区域，确保文本实时更新。 - 修复MeView显示问题，确保用户信息和动态内容正确加载。

+# 多语言问题修复计划
+
+## 问题描述
+项目配置了多语言支持，默认英文，但应用仍显示中文。原因是大部分视图使用 `NSLocalizedString`，它会读取系统语言设置而不是应用内保存的用户语言选择。
+
+## 解决方案
+
+### 1. 修复 LocalizationManager
+- ✅ 启用了注释的 String 扩展
+- ✅ 添加了全局 `LocalizedString` 方法
+- ✅ 添加了 `LocalizedTextModifier` 结构体
+
+### 2. 替换关键界面的本地化方法
+- ✅ LoginView - 应用标题、登录按钮
+- ✅ UserAgreementView - 用户协议文本
+- ✅ FeedListView - 页面标题、空状态、标语
+- ✅ IDLoginView - 标题、占位符、按钮文本
+- ✅ EMailLoginView - 标题、按钮文本
+- ✅ LanguageSettingsView - 添加测试区域
+- ✅ MeView - 用户昵称、ID显示、加载状态、错误信息
+
+### 3. 修复 MeView 显示问题
+- ✅ 修复 MainFeature 中的数据加载逻辑
+- ✅ 在 accountModelLoaded 中添加 MeView 数据加载触发
+- ✅ 确保 uid 正确设置时触发数据加载
+
+### 4. 新增功能
+- ✅ 全局 `LocalizedString(key, comment:)` 方法
+- ✅ String 扩展：`"key".localized`
+- ✅ 语言切换测试区域
+
+## 使用方法
+
+### 方法1：使用全局方法
+```swift
+Text(LocalizedString("login.app_title", comment: ""))
+```
+
+### 方法2：使用 String 扩展
+```swift
+Text("login.app_title".localized)
+```
+
+## 测试验证
+1. 在语言设置界面可以看到测试区域
+2. 切换语言后，测试区域的文本会实时更新
+3. 所有使用 `LocalizedString` 的界面都会正确显示选择的语言
+4. MeView 现在应该能正确显示用户信息和动态内容
+
+## 问题修复详情
+
+### MeView 不显示内容的问题
+**原因**：MainFeature 中只有当用户切换到 `.other` 标签页时才会检查 uid 并触发数据加载，但如果 accountModel 为 nil 或 uid 为 0，就不会加载数据。
+
+**解决方案**：
+1. 在 `accountModelLoaded` 处理中添加 MeView 数据加载逻辑
+2. 确保当 accountModel 加载完成且当前选中 MeView 标签页时，正确设置 uid 并触发数据加载
+
+## 后续工作
+- 继续替换其他界面的 `NSLocalizedString` 调用
+- 确保所有用户可见的文本都使用新的本地化方法
+- 测试各种语言切换场景
+- 验证 MeView 在不同登录状态下的显示
