chore: 发布v6.36.1版本，鸿蒙适配+隐私合规收尾

### 变更详情
1.  **多语言国际化**：新增`rejectAndExit`翻译键，覆盖14种语言的拒绝退出文案
2.  **鸿蒙端适配**：
    - 修复USB事件监听报错，仅Android端启用原生USB监听
    - 调整小部件管理页交互，鸿蒙端跳过Beta弹窗并显示"敬请期待"提示
    - 适配通用设置页和功能检查的鸿蒙端toast替代弹窗逻辑
    - 调整句子详情页"编辑"按钮的鸿蒙端交互
3.  **隐私合规优化**：
    - 移除剪贴板定时轮询，改为被动触发模式，仅在用户主动进入稍后读页面时检查剪贴板
    - 移除Android端非核心权限，精简权限声明
    - 新增启动页SplashActivity作为协议守门人，从根本上阻止敏感插件在协议前初始化
    - 为Android端引导页新增双按钮布局，优化未勾选协议时的用户操作引导
4.  **依赖与代码清理**：
    - 修复macOS端flutter_secure_storage插件导入路径
    - 简化字体导入逻辑，移除冗余的readAsBytes降级逻辑
    - 更新CHANGELOG文档，记录版本变更细节
