feat: MetonaAI Desktop 初始项目

- Electron + React + TypeScript 架构 - 三栏布局: Sidebar | ChatPanel | DetailPanel - 9 个内置工具 (文件系统/网络/记忆/命令) - SQLite 持久化 (better-sqlite3) - MUI 暗色/亮色主题系统 - Agent Loop ReAct 状态机引擎 - DeepSeek / Agnes AI / Ollama Provider 适配器 - MCP 协议集成 - 系统托盘 + 全局快捷键 - Tailwind CSS v4 + Tailwind Merge - 修复: Sidebar 缺失 TextField 导入导致黑屏
