ci: build multi-arch images on native runners

- split release metadata, web asset packaging and Docker image publishing into separate jobs

- build amd64 images on ubuntu-latest and arm64 images on ubuntu-24.04-arm instead of QEMU emulation

- push per-platform image digests and merge them into latest, release and sha manifests

- enable GitHub Actions cache scopes for each image and platform build
