- 新增 adr_watcher.py: SHA256 hash 监控 ADR 文件变更 - snapshot() 初始快照, detect_changes() 增量检测 - 识别 new/modified/superseded/deleted 四种变更类型 - _parse_status() 解析 ADR Status 字段 - 新增 partial_replanner.py: 局部重规划器 - replan() 仅生成受影响任务的替代计划 - _extract_stable_interfaces() 提取未受影响 DONE 任务接口约束 - 产出 replan-request.json 供 Arc 读取 - Eng monitor_engine 集成 ADR 检测: 每轮轮询调用 _detect_adr_changes() - Eng handle_adr_invalidation 集成 PartialReplanner 输出 - events.py 新增 ADR 变更相关事件常量 - task_graph.py apply_full_replace 保留 DISPATCHED, 不保留 INVALIDATED - 10 项补充测试全通过，含完整 ADR 流程场景 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
