scripts/build-arm64-image.sh automates the full linux/arm64 image build on Docker Desktop (WSL2): register qemu-aarch64 binfmt with the F flag so emulation works inside build containers, pre-pull the dotnet base images with resumable retries, build with dotnet restore routed through the host proxy and apt via the in-Dockerfile mirror, then docker save + gzip into a loadable archive. .gitignore now excludes the *.tar/*.tar.gz build artifacts, the qemu-*-static emulator binary, and the stray root package-lock.json.
