- 移除 3 处强制深色模式，用 @AppStorage 全局切换
- 设置页「外观」按钮实时切换深色/浅色/跟随系统
- 底部导航栏 inactive 颜色改为自适应 Color.zxF03
- 12 个子页面修复：保留返回按钮 + 消除顶部空白
- 新增 LearningSessionView/ReviewCardView/ActiveRecallView
- 新增 NotificationListView/SettingsView 等子页面
- 补全所有按钮 NavigationLink 跳转（0 个空白 action）
- KnowledgeBase 模型对齐服务器数据
- Info.plist 补充 CFBundleIdentifier + ATS
- 新增缺口分析文档 gap-analysis-1/2.md
