fix: corregir límite de sprites en SHAPE mode con muchas bolas

Browse Source 
GpuSpriteBatch::init() ahora acepta capacidad dinámica para soportar
--custom-balls N con N > 200000. El buffer se dimensiona a (N+1) quads,
reservando siempre un slot para el overlay. addFullscreenOverlay() calcula
overlay_index_count_ desde el delta real de indices_ en lugar de fijarlo
a 6 incondicionalmente. Engine calcula la capacidad correcta al init.
