Version: 0.9.1.dev.260406

后端：
  1.新建conv/schedule_persist.go：ScheduleState Diff 持久化，事务内逐变更写库，支持 place/move/unplace 三种操作（当前
  event source）
  2.新建conv/schedule_provider.go：ScheduleState 加载适配，从 DB 合并 existing events + pending task items
  3.新建dao/agent_state_store_adapter.go：Redis 状态快照存取适配，实现 AgentStateStore 接口
  4.新建service/agentsvc/agent_newagent.go：newAgent service 集成层，串联 LLM
  客户端、ScheduleProvider、SchedulePersistor 和 ChunkEmitter
  5.更新node/execute.go：接入 SchedulePersistor（写操作确认后持久化）、完善 confirm resume 路径（PendingConfirmTool
  恢复分支）、correction 机制增加连续失败计数上限
  6.更新api/agent.go + cmd/start.go：接入 newAgent service，完成 API 层路由注册
  7.新建node/execute_confirm_flow_test.go + llm_tool_orchestration_test.go：确认回路 7 个测试 + 端到端排课 5
  个测试全部通过
  8.新建newAgent/ARCHITECTURE.md + ROADMAP.md：全链路架构文档和缺口分析
  9.代码审查整理：提取 prompt/base.go（通用 buildStageMessages 等5个辅助）、tools/args.go（参数解析辅助）；write_tools
  尾部辅助移入 write_helpers；修复 queryRangeSpecific sb.Reset() 逻辑缺陷和 Unplace guest Duration
  未恢复；ScheduleStateProvider/SchedulePersistor 归入 state_store.go；emitter 内部 Build*Text 函数降级为私有
前端：无
