feat: 重写为 Tauri + React + TypeScript (v4.0)

完全移除旧 C+IUP 代码，改用 Tauri 2.x + React 19 + TypeScript + Rust 技术栈重写。功能与 v3.1 完全等价： - React 前端：Tailwind CSS 4、Zustand 状态管理、i18next 国际化 - Rust 后端：winreg 注册表读写、Win32 API FFI 调用 - 核心逻辑：StringList、UndoRedoManager、PathManager、Import/Export - 深色模式、中英文切换、键盘快捷键、合并预览 - 66 个 Vitest 单元测试 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
