🌱 Expanded Island + Procedural Growth System

ISLAND EXPANSION:
- Increased from 20x20 to 50x50 tiles (6400x6400px)
- World size: 10400x10400px (with ocean buffer)
- Irregular edges (procedural jitter system maintained)

PROCEDURAL GROWTH SYSTEM:
- Soil moisture grid (50x50) - tracks wet/dry tiles
- Grass growth: 30% chance if soil is wet
- Tree saplings: 10 placed on island edges
- Tree aging: sapling → medium (3 days) → large (7 days)
- Rainfall: 40% chance daily, wets 60% of tiles

LAYER SYSTEM (Z-ORDER FIX):
- LAYER_GROUND (-100): Foundation tiles
- LAYER_VEGETATION (1): Grass, bushes - below characters!
- LAYER_TREES (2): Trees
- LAYER_CHARACTERS (10): Kai, zombies - walks BETWEEN vegetation

GROWTH MECHANICS:
- Morning check every 60 seconds (1 in-game day)
- Grass fades in smoothly (2s animation)
- Trees progress: faza_1 → faza_2 → veliko
- Random grass types & sizes for variety

NATURE TAKES OVER:
- Island evolves procedurally over time
- Dark Gothic aesthetic maintained
- Living, breathing environment
