feat(sessions): 添加会话重命名功能和工具调用详情展示

- 实现了后端 API 接口 /api/sessions/:id/rename 用于重命名会话
- 添加了 Hermes CLI renameSession 方法来处理会话重命名逻辑
- 在前端添加了会话右键菜单，支持复制会话ID和重命名操作
- 新增重命名模态框组件供用户输入新标题
- 增强了消息项组件，支持展开查看工具调用的参数和结果详情
- 改进了工具消息的UI展示，包括运行状态指示器和错误标记
- 更新了会话列表显示源标识（如 Telegram、API 等）
- 优化了工具调用数据的映射逻辑，正确关联参数和执行结果
