Echo-Memory Diffusers pipeline

Community pipeline that overlays the Echo-Memory context_k1 row onto official Wan 2.1 1.3B Diffusers weights.

Paper: arXiv:2606.09803
Code: Echo-Team-Joy-Future-Academy-JD/Echo-Memory
Original keys: Echo-Team/Echo-Memory context_k1/epoch-0.safetensors
Converted transformer: this repo, context_k1-diffusers/diffusion_pytorch_model.safetensors

This is not the full multi-chunk camera-action / SSM research stack. It is the released DiT fine-tune remapped to Diffusers names (825 / 825 official Wan 1.3B transformer keys).
