dudu MVP：五端语音输入法初始提交

- server：Go 网关（WS 流式识别中继/计费配额/微信登录支付 mock/反馈/埋点），gummy provider 已真实联调
- desktop：Tauri 2（全局快捷键 push-to-talk/浮层/托盘/设置/登录购买/反馈/首启引导）
- android：Compose 主 App + IME（键盘内录音直传）
- ios：App + 键盘扩展（1A spike 实证键盘内不可录音，走 deep link 听写）
- design/design-pipeline：设计系统 + token 导出 iOS/Android 主题
- doc：前后端设计文档（HTML）；web：官网宣传页；todo：任务看板
