Add scripts/build-release-linux.sh for building musl-linked release archives (x86_64 and aarch64) on Linux. Uses `cross` for cross- compilation so no host toolchain beyond Docker/Podman is required. Also add mdrs-*.tar.gz and mdrs-*.zip to .gitignore to prevent generated release archives from being tracked. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
