v0.1.6: 时轮与造化（GameClock/RngHub/时节/年轴/保护）

- 统一时轮 GameClock：七 phase 注册制（production/aging/cultivation/missions/
  events/diplomacy/epilogue） + 年首三钩子（婚配→岁贡→族簿）；advanceMonth 化作薄壳；
  新增系统只注册不改本体；alive 守卫、随机序、族簿时序均与重构前逐一等价
- 金钟罩：3 枚 seed × 560 月指纹常驻（重构前后已验证同哈希；时节属有意变更后重固化）
- 统一随机 RngHub：开局播种（crypto UV）、音效白噪独立流、引擎 rng 带 nextCount 审计；
  全工程拔除逻辑侧 Math.random
- 时节系统：春夏秋冬乘子（春田+10%/夏修+5%/秋市+5%/冬闭+8%）入生产与修炼
- 崩溃保护：advance 异常自动存『出险前』档 + 停速提示回档
- 性能预算：dev-only 单 tick>60ms 报最慢 phase
- 横轴年表：十年一格大事/生殇聚合 + 春秋原年轴视图
- 测试 197→225（时钟/收集器/四季/年轴/效果全矩阵/死局链/残留防御）
