feat: CradleScene + UIScene + GameScene cycle integration

Scene integration for the Great Cycle system:
- CradleScene: shows "Великий Цикл N: Тема | Ран X/7", narrative quote
- UIScene: cycle info bar and run phase display below health
- GameScene: world trace spawning (ruins/markers from past runs),
  trace glow rendering, death position recording, cycle info to registry,
  biomeId + worldSeed passed to RunState
- Scene flow: Fractal → RenewalScene (on 7th run) → Cradle
