- ToolLoop 增 history 参数（既往轮次折叠为对话上下文，近 6 轮）
- 会话制：AgentSession/SessionStore 持久化 agent_runs/sessions/{sid}.json，
/agent/sessions CRUD + /agent 带 session_id（继承会话工作区与执行者配置，busy 并发控制）
- POST /agent/{id}/cancel：取消运行中任务
- AgentView 重构为对话式：会话列表 + 居中消息流（用户蓝气泡/助手白卡）+ 底部 composer
（工作区/执行者/命令 chips，Enter 发送，运行中红色停止钮），工具过程折叠收纳
- 工具步数统计统一至事件写入层并透出 status.tool_calls
- fix(tests): 会话存储测试隔离，防测试数据泄漏进真实 sessions 目录
- 测试 +4，全量 281 passed
