test: 测试矩阵扩至 861 项（参数化全覆盖）

新增 5 个矩阵套件：
- data-matrix 242：物品/功法/建筑/秘境/敌人/势力/事件选项/职事/秉性/灵根/境界/时节 逐行
- balance-edge 81：年龄/修为/气血/库存/金钱边界、传承谱系年轴、境界战力、突破矩阵、评分分档、难度
- world-matrix 21：多 seed 长跑、继承链多路径、gameOver 守卫、岁簿/大比/回声周期、确定性复跑
- rng-matrix 38：多种子性质、范围分桶、RngHub 回放/隔离、state 拷贝、pick/shuffle 保集
- api-matrix 32：act 全目录逐项、query 全 ref、subscribe 全事件矩阵
- event-state-matrix 193：逐事件逐选项应用不破、effect 引用、职事上限/寄读、志向、normalize 残缺矩阵、动态事件

引擎附带优化：月底 clampState（修为/气血/库存/金钱永不越界——负血量负库存负钱被矩阵钓出后修复）
总测试 256 → 861；金钟罩复验通过（clamp 零漂移）
