* refactor: update water texture * feat(gameplay): implement transparent block rendering with depth sorting * fix(world): use camera pos for distance calculations, make water passable * refactor(player): use ivec3 for block pass check * feat(camera): add underwater detection * feat(renderer): add underwater effect with framebuffer post-processing * feat(block): add gas property and refactor solid block check * fix(assets): set leaf block transparency to false * fix(block): set leaf as transparent
