Fixes #1164

Replace the single amd64 build job with a matrix strategy that runs native
builds on GitHub-hosted runners for each architecture (ubuntu-24.04 for amd64,
ubuntu-24.04-arm for arm64). A separate manifest job merges the per-arch images
into multi-arch tags via docker buildx imagetools create.

Both the default and no-tls image variants are built for each architecture,
producing four parallel build jobs. Cache keys are scoped per-arch and
per-variant to prevent collisions.

The Dockerfile requires no changes. All base images and build dependencies are
available for both architectures.

Tested at ghcr.io/nmarley/zaino:0.3.1-rc.1 with successful native builds
and verified multi-arch manifests for both linux/amd64 and linux/arm64.

Add multi-arch Docker images, particularly ARM64 alongside the default AMD64.
