test: conftest ir_data 防御 list-type section + normalize 异常回退 - Closes #70

开发流程新增步骤 5-6：运行完整 pipeline + e2e 验收 (Layer A+B+C)，
防止修复引入回归。

 - 关注 IR 一致性：对同一输入的多次运行结果应尽量稳定
 - 关注功能覆盖率：确保 IR 覆盖了输入文档中的功能点
 - **验证是实际功能验证，不是 dry-run**：`pytest` 通过只是门槛，必须用真实输入文档实际运行 pipeline 确认功能生效
+- **PR 前必须通过 e2e 验收 (Layer A+B+C)**：防止修复引入回归。若无法运行完整 pipeline（API 不可用等），至少在 PR 描述中注明
