feat(v2): T11 改进治理与演示交付——对照门禁、泄漏作废、三模块演示脚本
覆盖 AC-15/16/34/37/41（BR-15/16/40、E-11/24）。
后端：
- contracts/improvement.py：ImprovementCandidate + ContrastReport/ContrastMetrics。
零分母不得给比率或覆盖率（样本不足不是 0%）；非独立评测不得给改进/退化结论；
已发布必须引用既有不可变版本；没有对照证据不得进入待审核或已发布。
- services/improvements.py：
· evaluate_contrast 在服务端判定泄漏——预测锁定前读到标签即整次评测作废（E-11），
保留集来源进开发集的样本作废并单列，指标按分子/可观察分母/覆盖率/未观察分开报；
· transition 状态机：draft→evaluating→ready→in_review→approved→released，
自批拒绝、退化与结论不明拒绝发布、发布幂等且只引用既有版本、撤回只影响新运行。
- api/prescreen.py：候选列表、提出与状态机三个端点；评测请求体提交样本，
泄漏与指标一律由服务端计算，不接受客户端交来的"成品报告"。
- contracts/prescreen.py：补 E-11/E-24 错误码与 409 映射。
前端一致性修正：
- src/lib/prescreen-run.ts 的呈现判定改用后端既有词汇
（empty/list/grouped/radar/faceted，与 services/review_plan.presentation 一致），
避免前后端各一套判定导致界面画出后端判定为不该画雷达的图。
演示交付：
- scripts/xingbang_prescreen_demo.py：按 08 §7 八步演示，只驱动已实现入口，
未实现的步骤（批量清单、历史提炼、卡片治理）如实标注原因；
工程演示与模型效果分列，本地专项/Jev/真实概率一律标未验证或未接通。
- backend/test_demo_script.py：冒烟断言八步状态、未实现原因与分列口径。
验证：backend 全量 unittest 519 项 OK；前端 npm run build 通过。
