Version: 0.9.2.dev.260406
后端：
1.Chat 四路由升级（二分类 chat/task → 四路由 direct_reply/execute/deep_answer/plan）
- 新建model/chat_contract.go：路由决策模型，含 NeedsRoughBuild 粗排标记
- 更新node/chat.go：四路由分流；新增 deep_answer 深度回答路径（二次 LLM 开 thinking）
- 更新prompt/chat.go：意图分类 prompt 升级为四路由 prompt；新增 deep_answer prompt
2.粗排节点（RoughBuild）全链路
- 新建node/rough_build.go：粗排节点，调用注入的算法函数，结果写入 ScheduleState 后进 Execute 微调
- 更新graph/common_graph.go：注册 RoughBuild 节点；Chat/Confirm 后可路由至粗排
- 更新model/graph_run_state.go：新增 RoughBuildPlacement/RoughBuildFunc 类型；Deps 注入入口
- 更新model/plan_contract.go：PlanDecision 新增 NeedsRoughBuild/TaskClassIDs 字段
- 更新node/plan.go：plan_done 时写入粗排标记和 TaskClassIDs
3.任务类约束元数据（TaskClassMeta）贯穿 prompt → tools → 持久化
- 更新tools/state.go：新增 TaskClassMeta；ScheduleState.TaskClasses；ScheduleTask.TaskClassID；Clone 深拷贝
- 更新conv/schedule_state.go：加载时构建 TaskClassMeta；Diff 支持 HostEventID 嵌入关系
- 更新conv/schedule_provider.go：新增 LoadTaskClassMetas 按需加载
- 更新model/state_store.go：ScheduleStateProvider 接口新增 LoadTaskClassMetas
- 更新prompt/base.go：renderStateSummary 渲染任务类约束
- 更新prompt/plan.go：注入任务类 ID 上下文和粗排识别规则
- 更新tools/read_tools.go：GetOverview 展示任务类约束
- 更新model/common_state.go：CommonState 新增 TaskClassIDs/TaskClasses/NeedsRoughBuild
4.Execute 健壮性增强（correction 重试 + 纯 ReAct 模式）
- 更新node/execute.go：未知工具名/空文本走 correction 重试而非 fatal；maxConsecutiveCorrections 提升为包级常量；新增无 plan 纯ReAct 模式；工具结果截断；speak 排除 ask_user/confirm
- 更新prompt/execute.go：新增 ReAct 模式 system prompt 和 contract
5.写入持久化完善（task_item source + 嵌入水课）
- 更新conv/schedule_persist.go：place/move/unplace 支持 task_item source，含嵌入水课和普通 task event 两条路径
- 新建conv/schedule_preview.go：ScheduleState → 排程预览缓存，复用旧格式，前端无需改动
6.状态持久化体系（Redis → MySQL outbox 异步）
- 更新dao/cache.go：Redis 快照 TTL 从 24h 改为 2h，配合 MySQL outbox
- 新建model/agent_state_snapshot_record.go：快照 MySQL 记录模型
- 新建service/events/agent_state_persist.go：outbox 异步持久化处理器
- 更新cmd/start.go + inits/mysql.go：注册快照事件处理器 + AutoMigrate
- 更新service/agentsvc/agent_newagent.go：注入 RoughBuildFunc；outbox 异步写快照；排程结果写 Redis 预览缓存
7.基础设施与稳定性
- 更新stream/sse_adapter.go：outChan 满时静默丢弃，保证持久化不被 SSE 阻断
- 更新service/agentsvc/agent.go：新增 readAgentExtraIntSlice；outChan 容量 8→256
- 更新node/agent_nodes.go：Chat 注入工具 schema；Deliver 改 saveAgentState 替代 deleteAgentState
