Stacy Olivas 5b6f2829b8 infra: Docker multi-arch build with SBOM and provenance
Add .github/workflows/docker-build.yml triggered on push to main and
version tags. Builds linux/amd64, linux/arm64, and linux/arm/v7 via
QEMU. Attaches SBOM and provenance attestations to the image manifest.
Update Dockerfile with non-root user and current Python base image.
