nav: 统一 NavNode schema + runtime/roadmap 分离 + 城市补父级

- navigation/nav-schema.js: 统一 NavNode schema 定义
- navigation/runtime-nav.js: MVP runtime（仅 6 城市 active）
- navigation/future-catalog.js: 路线图数据（不进 runtime）
- 旧索引文件标注 @deprecated，重定向到新路径
- 6 城市补 countryId/regionId
- game-design 明确 MVP vs V1.1+ 导航边界
