feat: 全量日志接入 + 日志服务重构（非阻塞）

log-service 重构：
- DOM 渲染改用 requestAnimationFrame 批量队列
- 全程 try-catch，任何异常都不阻塞主流程
- 新增 logConnection/logModel/logSession/logMemory/logRAG/logSetting/logIPC/logInit 便捷方法

全量接入（12 个文件）：
- header.ts: 连接状态变化（connected/disconnected/error）
- model-bar.ts: 模型列表加载、模型切换、能力检测结果
- settings-modal.ts: 所有设置变更（系统提示词/上下文/温度/工具调用/命令执行/记忆）、显存释放、导出/导入
- tool-confirm-modal.ts: 工具确认弹窗、确认/取消操作
- memory-manager.ts: 记忆初始化、新增/删除、自动提取
- tool-registry.ts: 工具执行异常
- rag.ts: 文档分块、向量检索
- kb-modal.ts: 知识库创建、文档上传、批量上传
- history-modal.ts: 会话加载、会话删除
- main.ts: 应用初始化各阶段、桌面集成、菜单/托盘操作、新建会话
- input-area.ts: 消息发送、流式完成/错误、文件/图片添加、Agent Loop 错误
