- js/app.js:165-260, 310-420, 560-893：重构模式切换与流式渲染逻辑；引入 renderSvgViewerForMode 分离各
模式历史与SVG；通过 buildActionToolbar 和 renderConversationHistory 仅为最新 AI 气泡保留“重新生成”；
新增 setSendButtonState、startStreamingMessage、cancelActiveStream 实现终止按钮与流式中断，回滚后同
步复位查看面板。
- js/utils.js:24-334：增强 parseSVGResponse 容错截断SVG/反引号；StreamProcessor 增加完成态管理；
createStreamRequest 返回 {cancel, finished} 并支持 AbortController，保证中止时回调依然收尾。
- js/apiclient.js:150-208：流式接口返回新的句柄对象而非简单等待，使前端可触发中止，同时保持异常转换。
- css/style.css:220-224：去除悬浮显隐，操作按钮常显，并保留色彩过渡以提示交互。
- js/app.js:900-970：regenerateMessage 改用“处理中”状态并重绘气泡（按最新可见状态），避免历史重复
生成。
