Initial commit: SparkyUI - ComfyUI for DGX Spark (Blackwell GB10)

Docker-based ComfyUI setup for NVIDIA DGX Spark ARM64 + sm_121:
- CUDA 13.0.2 base (required for compute_121 support)
- PyTorch 2.9.1+cu130 ARM64 wheels
- SageAttention compiled with TORCH_CUDA_ARCH_LIST="12.1"
- Triton/torch.compile disabled (no sm_121 support yet)
- ComfyUI-Manager auto-installed at runtime
- Configurable model/data paths via .env
