feat(chat,todo): 小埃同学对话窗口与待办窗口

Chat: - DTK2 窗口：左侧会话列表 + 右侧对话区 + 输入框 - DeepSeek / 自定义 API，SSE 流式输出，首字即显示 - 会话持久化到 chat.json，新建/切换/标题自动生成 - 设置对话框：API Key、API 地址、模型、系统提示，含开通指引 - 拖放：左侧空白=新建对话，左侧会话=指定会话，右侧对话区=当前会话 - Ctrl+Enter 发送，错误以消息形式回显 Todo: - 待办窗口（layer-shell，不抢焦点、不进 dock），复选框/删除/新建 - 待办持久化 todo.json，--todo 打开，独立 desktop 入口其他: - desktop 入口改为打开对话窗口，--chat 参数 - 单实例消息支持 show/todo/chat
