feat: Evolution Engine Phase 3-5 — WorkflowComposer+FeedbackCollector+EvolutionMiddleware+反馈闭环

Phase 3:
- EvolutionMiddleware (priority 78): 管家对话中注入进化确认提示
- GrowthIntegration.check_evolution() API 串入

Phase 4:
- WorkflowComposer: 轨迹工具链模式聚类 + Pipeline YAML prompt 构建 + JSON 解析
- EvolutionEngine.analyze_trajectory_patterns() L3 入口

Phase 5:
- FeedbackCollector: 反馈信号收集 + 信任度管理 + 推荐(Optimize/Archive/Promote)
- EvolutionEngine 反馈闭环方法: submit_feedback/get_artifacts_needing_optimization

新增 12 个测试（111→123），全 workspace 701 测试通过。
