- Introduce Ocean biome enum, builder, and detection logic. - Add ocean water building to all existing biomes and modify heightmap thresholds for low mountainous areas. - Skip cave and river generation in Ocean (and River) biomes; avoid carving water blocks. - Comment out border blending call and update block fill logic.
