Subject: [PATCH] feat: add SD 1.5 model and update AnimateDiff workflow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Changes:
- Added Stable Diffusion v1.5 model to comfyui_models.yaml
  - Required for AnimateDiff motion modules (mm_sd_v15_v2.ckpt)
  - Size: 4GB, VRAM: 8GB
- Updated AnimateDiff workflow to use SD 1.5 instead of SDXL
  - Changed checkpoint from sd_xl_base_1.0.safetensors to v1-5-pruned-emaonly.safetensors
  - Updated VRAM requirement from 18GB to 12GB
  - Updated model requirements in metadata

AnimateDiff v15 motion modules are not compatible with SDXL.
This resolves: "Motion module 'mm_sd_v15_v2.ckpt' is intended for SD1.5 models"
