feat(gamedev): comfyui_build_item_icon_workflow — iconos de inventario

Browse Source 
Builder puro hermano de pixelart/sprite_sheet/seamless_tile: arma el dict
(API format) para iconos de items (espada/pocion/anillo/libro/escudo).
txt2img cuadrado + prompt scaffold de icono + LoRA estilo opcional + Rembg
(alpha). Compone comfyui_build_txt2img_workflow + comfyui_inject_lora.

Test offline 7/7 verde. Generacion real verificada (icono de pocion de
salud centrado, RGBA fondo recortado, prompt_id 70b7a52a, 512x512 SD1.5).
Fila en docs/capabilities/gamedev-2d.md. Detalle en report 0147.
