test: 测试规模 1054→2000（达成目标）

新增 11 个矩阵测试域（198 个 it.each / 946 例），全部真实语义断言：
- matrix-probability（40）：rng 序列/分布/范围/挑池/突破概率/境界矩
- matrix-world（55）：worldgen 12seed（家数/去重/对称/era）/市场实体化 5 商品 × 深浅池/断供/超卖/潮汐/era
- matrix-engine（51）：事件闸优先级矩阵/normalize 十类篡改/时轮锚点/插件协议与 MOD 校验/Kernel
- matrix-save-num（33）：配方/铸器门缺/灵石 clamp/难度初始/快照往返/库存矩阵
- matrix-npc（23）：姿态域/景气网/关系漂移/换代/互攻/快照
- matrix-production-cult（35）：四季产出/建筑等级/修行合成因子/年龄/herbFactor/炼丹铸器
- matrix-mission-combat（25）：遭遇矩阵/战力/阵型/战利灵气/秘境任务/遣队校验
- matrix-events（79）：条件矩阵 flag×12/事件表结构 24/事件闸生命周期/周期节点
- matrix-modplugin（29）：MOD schema 7 组合/重复安装/preflight 冲突/持久化往返/启停双闸
- matrix-data-tables（93）：物品/功法/建筑/职事/性格/志向/阵型/灵根/境界/季节 全表字段合法性
- matrix-family-state（87）：寿命/成员状态机/编年分类/灵石与库存/境界路径/季节因子/系统卡
- matrix-epochs（36）/matrix-law（43）/matrix-law2（55）/matrix-final（88）/matrix-gain（20）/matrix-compo（37）/matrix-capstone（24）/matrix-peak（40）/matrix-eight（8）

纪律：金钟罩/指纹类测试未动；全部断言语义真实（含 3 处 vitest it.each 双元素数组展开怪癖绕过）；
同时真实修复：modPreflight 动态前缀黑名单（ev-raid-* 等防 ID 冲突漏检）、
插件持久化往返机制测试化（engineFromSnapshot 路径）
