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

/**

* Agnes AI Provider Adapter
|
||||
*
|
||||
* OpenAI 兼容 API，免费使用。
|
||||
* 支持 Tool Calling、Thinking 模式、512K 上下文、多模态（图片 base64）。
|
||||
*
|
||||
* 差异于 DeepSeek：
|
||||
* - Thinking 模式使用 chat_template_kwargs（非 thinking 字段）
|
||||
* - 图片使用 base64 格式（与 Ollama 一致，通过 images 字段传递）
|
||||
* - 512K 上下文，65.5K 最大输出

- If you detect potential harm in the requested action, refuse and explain why
