phase 6: escalation effects + enhanced crisis system

- Add escalation effects module: creature speed/aggro/damage multipliers,
  reaction instability, environmental damage — all scale 0→1
- Add getCrisisPlayerDamage/getCrisisTint to crisis module
- Integrate escalation effects into GameScene (env damage at high entropy)
- Dynamic crisis overlay tint that intensifies with progress
- Phase indicator shows entropy %, aggression multiplier, crisis status
- 14 new tests for escalation + crisis damage/tint (349 total)
