主要改进： - 新增 REST API 任务管理接口 (/api/tasks) - 实现 150ms 轮询机制，提供流畅的流式输出体验 - 支持页面刷新后自动恢复任务状态 - WebSocket 断开时检测 REST API 任务，避免误停止 - 修复堆叠块融合问题，刷新后内容正确合并 - 修复思考块展开/折叠逻辑，只展开正在流式输出的块 - 修复工具块重复显示问题，通过注册机制实现状态更新 - 修复历史不完整导致内容丢失的问题 - 新增 tool_intent 事件处理，支持打字机效果显示 - 修复对话列表排序时 None 值比较错误 技术细节： - 前端：新增 taskPolling.ts 和 task store 处理轮询逻辑 - 后端：TaskManager 管理任务生命周期和事件存储 - 状态恢复：智能判断是否需要从头重建，避免内容重复 - 工具块注册：恢复时注册到 toolActionIndex，支持状态更新 - Intent 显示：0.5-1秒打字机效果，历史加载直接显示 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
