Adds a multi-stage Docker build that compiles SageAttention 2.2/2++ from the upstream repository head into a wheel using nvcc, then installs it into the slim runtime to keep images small. Ensures the builder installs the same Torch CUDA 12.9 stack as the runtime so the compiled extension ABI matches at load time. Shallow clones the SageAttention repo during build to always pull the latest version on each new image build. Updates the container launch to pass --use-sage-attention so ComfyUI enables SageAttention at startup when the package is present. This change keeps the runtime minimal while delivering up-to-date, high-performance attention kernels for modern NVIDIA GPUs in ComfyUI.
