fix: collision tunneling, spawn at surface, physics substepping

Browse Source 
- Fix: rewrite resolve_grid_collision to push body out of solid cells
  when center is inside (was only pushing to small radius from center)
- Fix: max velocity clamp (0.8) + 4x substepping prevents tunneling
- Fix: player/goblin spawn at terrain surface instead of mid-air
- Fix: gravity reduced from 0.3 to 0.08 for substepping
- Add: headless mode (--headless-ticks N) dumps grid state to file
- Add: velocity zeroing on collision for stable resting
