feat: P1-19 P1-20 实现 - 边界测试强制 + 高风险审计 + UI Skill 路由
P1-19.1: Arc 边界测试强制 - TaskNode 新增 test_required 字段 - _inject_boundary_tests() 为每个模块注入接口测试和单元测试任务 - Done When 验证必须包含"测试通过" P1-19.2: AirRvr 高风险审计 - 新增 HighRiskAudit, HighRiskFinding 数据类 - ReviewReport 新增 highRiskAudit 字段,含 lifecycle/nullPointer/danglingPointer/exceptionSafety/concurrency + overallRisk + deliveryVerdict - 序列化/反序列化支持 P1-19.3: block-release 集成 - dispatch_worker_group() 派发前扫描最新审查报告 - deliveryVerdict=block-release 时阻止所有后续派发 - 记录 eng.blocked 事件 P1-20: frontend-design Skill 集成 - is_ui_task() UI 任务检测 - ensure_frontend_design_skill() 自动安装 Skill - route_ui_task() UI 任务路由决策 - enter_worker() 集成 UI 检测,skill 不可用时阻止执行 - commands/do.md 更新 UI 处理说明 - SKILL.md 新增 INV-12/INV-13/INV-14 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
