后端：
1.粗排链路收口（按 task_class_ids 精确加载 ScheduleState + 规划窗口抗脏数据）
  - 更新conv/schedule_provider.go：新增 LoadScheduleStateForTaskClasses；优先按本轮任务类加载窗口；buildWindowFromTaskClasses 改为逐条过滤坏日期，避免 DayMapping 被全量任务类污染
  - 更新model/state_store.go：新增 ScopedScheduleStateProvider 可选接口
  - 更新model/graph_run_state.go：EnsureScheduleState 首次加载时优先走 scoped provider，再做 scope 裁剪
2.粗排建议态语义统一（pending/existing → pending/suggested/existing）
  - 新建tools/status.go：统一 IsPendingTask / IsSuggestedTask / IsExistingTask / scope 过滤逻辑
  - 更新node/rough_build.go：粗排回写后任务显式转 suggested；pending 统计仅看“真实 pending”
  - 更新tools/state.go：ScheduleTask.Status/Slots/Duration 注释补齐 suggested 语义
  - 更新tools/read_helpers.go + read_tools.go：overview/list_tasks/task_info 支持 suggested 展示；占用计算按“已落位任务”统一处理
  - 更新tools/write_helpers.go + write_tools.go：place/move/swap/unplace 全量切到 suggested/existing/pending 新语义
  - 更新tools/registry.go + SCHEDULE_TOOLS.md：工具描述、参数枚举、文档口径同步到 suggested 语义
  - 更新conv/schedule_preview.go：预览层统一通过 IsSuggestedTask 输出 suggested，兼容旧快照
  - 更新service/agentsvc/agent_newagent.go：预览 debug 摘要改为 pending/suggested/existing 三态统计
3.粗排调试增强
  - 更新node/rough_build.go：新增 applied/day_mapping_miss/task_item_match_miss 统计及样本日志，便于排查 placement 未落回 state 的根因
