feat: 任务书 10，submissions 模块与 materials 修改

- 新增 src/submissions：先程序检查（14 条跨字段规则、不许改的文件、代码存不了、指标编号占用、提案数上限），全过再问 Jev；退回原因列出该写的全部编号；回应/统一拼冻结协议主体只在这一处；核验、消融核验通过没有。
- materials：挑刺单写"现在交什么"；退回按阶段、作者、种类、对象找（ledger 退回记录加 target，表结构版本 4）；核验材料去掉 Jev 预扫；信念本写合法化；删"本该关着"；消融核验不通过可重做，不跑的格从 cellNotRun 事件读原因。
- 用户 2026-10-03 定：冻结协议去掉 replies、replyBody，第二次预测的答复从已公开的回应或统一读；takenMetricIds 加两个保留键；解释一律交 cells；Jev 退回只列判"是"的几问、用英文问题名。
- jev 判重材料带 keySettings；读代码工具删 offset；三处旧说法改正。
- 文档：结构.md 第四、七、八部分，WORK_LOG。
