test: 测试矩阵扩至 161 项（深度审计 + 5 处缺陷修复）

新增测试矩阵（12 文件 / 161 cases）：
- rng 12 / data 18 / pcgen+cultivation 20 / economy 12 / combat+missions 24
- marriage+diplomacy 13 / events 12 / world+lifecycle 8（含镜像一致）/ save 4+5 / audit 8

审计带出并修复的真实缺陷：
1. Rng.pick 空数组未报错（防空白数组进而崩溃难查）
2. combatPowerOf 未应用功法悟道品阶战力加成（0.1.2 设计缺口）
3. 重伤者即使不代表伤状态仍按满速修炼（health 进修炼公式）
4. 寡妇/鳏夫无法再婚：候选列表放着人执行层却拒婚（spouseId 死旧契约）
5. isWidowed 参数契约陷阱：传 id 静默 false（升级接受 Character|Id 双签名）
