Replace sequential QEMU-emulated builds with parallel native builds using a matrix strategy (ubuntu-latest for amd64, ubuntu-24.04-arm for arm64) and manifest merging. This eliminates the ~5-10x QEMU overhead and should cut Docker build time roughly in half. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
