Subject: [PATCH] Build multi-arch images so pulls work regardless of
 runner/host CPU

The first successful Gitea-side publish only produced a manifest for
whatever architecture the self-hosted Actions runner happens to be,
which didn't match the amd64 ZimaOS host pulling it ("no matching
manifest for linux/amd64"). Adds QEMU + Buildx setup and builds for
linux/amd64 and linux/arm64 explicitly so the published image works on
any host regardless of what CPU built it.
