v0.1.7: 仙门之钥（门面化/能力注册表/数据包/开发者面板）

- GameFacade 统一门面：act(23 种动作白名单)/query(6 类只读快照)/subscribe(七大事件协议)/
  about(版本+模块清单+数据包指纹)；UI store 接入门面（act 直达，散装调用收口）
- CapabilityRegistry：12 张能力卡（id/name/version/desc/hooks），world.systems 启停即拔插，
  时钟按能力开关过滤（禁修炼则无人精进…沙盒玩法）；sysChanged 广播
- DataPackRegistry：默认包与静态数据同引用（金钟罩零漂移），override/reset/fingerprint，
  高频读口 6 处迁移 pack()——未来 MOD=注入数据包覆写
- 开发者面板：设置页系统仪表盘（清单+启停开关+警示文案）
- 测试 225→239（能力清单/拔插分殊四路/广播幂等/包覆盖物价/act 目录/query/协议退订/about/
  金钟罩复验零漂移）
