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

Browse Source 
- 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
