GODOT 4 TILESET GENERATOR
Converts Phaser/Tiled tilesets to Godot 4 TileSet format (.tres)

Features:
- Water_Animated → AnimatedSprite frames (150ms)
- Grass_Animated → AnimatedSprite frames (200ms)
- Tall_Grass → Harvestable tiles with animations
- Terrain Sets → 47-tile wang blob auto-tiling

Usage: python3 scripts/godot_tileset_converter.py
