feat(ml): comfyui_build_img2vid_workflow builder img2vid SVD (API format)

Browse Source 
Builder puro que construye el dict de un workflow ComfyUI img2vid (Stable Video
Diffusion) en API format a partir de una imagen estatica. Cadena de 7 nodos:
ImageOnlyCheckpointLoader(svd.safetensors, todo-en-uno) + LoadImage ->
SVD_img2vid_Conditioning -> VideoLinearCFGGuidance -> KSampler(denoise 1.0) ->
VAEDecode -> SaveAnimatedWEBP. SVD condiciona por CLIP_VISION de la imagen (sin
prompt de texto); movimiento via motion_bucket_id.

class_type/inputs verificados contra /object_info del servidor vivo. Validacion
estructural con comfyui_validate_workflow: 0 errores. 4 tests verdes. Sin submit
de generacion (GPU en uso por otro agente).
