Add pixel art sprites for charger, spawner, and laser turret

Browse Source 
Replace colored-rect placeholder rendering with proper 16x16
spritesheet art. Charger: orange armored rhino with horn, eyes,
walk cycle (row 7). Spawner: purple hive pod with glowing core
and tendrils (row 8). Laser turret: angular metallic housing
with red lens that brightens when firing (row 8). All three
retain colored-rect fallback when spritesheet is unavailable.
