v0.1.3: 深度审计修复（兼容/血缘/联姻/远征/数值）

- 旧档兼容：<0.1.1 存档缺 finance/yearStats/yearlyReports 字段加载归一化（防运行期崩溃）
- 血缘防护：同母异父兄妹也禁止婚配（指婚/媒人/联姻三路齐封）
- 联姻修正：一家一姻亲（allied 锁），再娶再嫁不再无限刷；男儿娶亲也子孙来归
- 和约语义：议和强推关系至 +30（真停战），不再打完一场还是仇雠
- 远征收队：任务完成/召回自动释放队员闲居；重伤者当月离队疗伤、不足定员提前撤队（修复人员永久困远征/卡状态）
- 数值：婴儿夭折率 2%→0.8%；劫掠队强度 0.9→0.78；事件负资源钳制不为负灵石
- UI：丹药按钮显示持有并禁点；点将模式支持取消重选；设置页移除摆设项
- 新增 audit 套件：8 项（含 600 月长跑耐力）总测试 38→46 全绿
