Every image build now carries <version> and the immutable
<version>.<unix-ts>; latest goes to the newest release on main, each
prefix (2, 2.3) to the newest release starting with it, and stable to the
release the git tag stable marks, which "Mark stable commit" sets only
after all tests passed.
publish-containers.yml runs daily at 03:00 UTC and on workflow_dispatch.
A rebuild publishes the newest release and, when the git tag stable sits
on an older one, that release too, so both get base-image security
updates. compute-publish-container-info.sh emits the release list with
each release's moving tags; image.sh takes them as --aliases instead of
--stable.
A platform build whose installed package set equals the published
<version> pushes nothing, and a merge whose image index equals the
published one only moves the tags not yet on it, without a new stamp.
Only vX.Y.Z tags count as releases; v2.4.0-rc1 no longer moves 2 or 2.4.
The build scripts come from the release commit: releases tagged before
this change keep the old scripts until a newer release replaces them.
tests/integration: 22 tests for release choice, aliases, the stable
rebuild, the push skip and the triggers.

Each distro now builds amd64 on ubuntu-latest and arm64 on
ubuntu-24.04-arm instead of emulating arm64 under QEMU. image.sh gains
--platform, which pushes one <version>-<arch> tag, and --merge, which
joins those tags under the release, stable and alias tags with
buildx imagetools. The workflow splits into prepare, build and merge
jobs; scripts/build/publish.sh follows the same sequence locally.

Trigger container publishing via workflow_run on "Mark stable commit", gate on success,
checkout the workflow_run head SHA, force-refresh tags, and derive version from the v* tag
pointing at the tested commit to correctly detect and publish stable images.

Switch publish-containers workflow from workflow_run to direct v* tag triggers,
remove obsolete workflow_run logic, simplify version detection via GITHUB_REF_NAME,
and keep stable-tag detection aligned with the stable ref.

Introduce a dedicated publish-containers workflow triggered after stable releases.
Unify container build and publish logic via scripts, add buildx-based multi-tag publishing,
default base image resolution, and Arch alias tags for latest/version/stable.
