feat: P1-21 ADR 变更级联失效 — 架构变更自动失效已完成任务

- TaskNode 新增 adr_refs 字段（ADR→任务溯源链） - 新增 INVALIDATED 状态，允许覆盖 DONE/DISPATCHED - TaskGraph.invalidate_by_adr() 级联失效 + BFS 下游传播 - PlanDelta 新增 rollback_ref（回滚快照引用） - CascadeReport 数据结构（失效统计 + 任务ID列表） - Eng dispatch_frozen 冻结调度，ready_tasks() 返回空 - handle_adr_invalidation() 10步处理流程（含 git revert） - unfreeze_after_replan() Arc 重新规划后解冻 - AirRvr check_invalidated_cleanup() 检查旧代码残留 - INV-15 + L1 保障项 15 写入 SKILL.md - 11 项功能测试全通过，含 ffmpeg→gstreamer 完整场景 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
