v0.1.24: 寰宇初构——世界种子生成器 + 插件时轮锚点（1034 全绿）

【世界种子生成器（NPC 数量不再定死）】
- sim/worldgen.ts：generateWorld(seed) 确定性塑造天下——NPC 4~8 家随机
  （老牌世家模板 + 词库组合新贵，名字去重）、初始关系网（1-2世仇+1盟友）、
  开局 era 三态、区域风味、市场偏移 ±15%
- 独立派生 rng（seed::worldgen）——World.rng 主序列零消耗：同 seed 世界可重放、
  玩法随机序列不受生成器移动（金钟罩玩法序保护）
- state.worldGen 落档（normalize 旧档按 seed 重放=同世界，存档兼容）
- creation 初始化 npcFamilies/initSim 关系网/era/池偏置全走 worldgen——开局即恩怨
- 局内补位目标 = 开局家数（4~8），生灭闭环持续

【插件深化（0.1.24 第二组钩子）】
- PluginContext.beforePhase/afterPhase（时轮锚点：phase 前后挂勾，卸载全摘）
- PluginContext.addNpcTemplate（世界模板注入——词库插件化）
- plugin-public 文档同步；示例 Plugin 契约升级

【测试适配（世界名单随机化）】
- 静态 npc id 假设全面改动态取家（anyNpc helper 共享）；
- 难度梯度用例改「同 seed 不同难度」比较；worldgen 确定性/范围/去重/关系对称 7 例

【测试】1034 全绿（45 套件）；金钟罩 0.1.24 基线固化（worldgen 随机世界）+ worldAnnals 等；
