Extends the ghcr offline-install path to every install-apt-deps consumer
that was still on plain apt, and publishes the bundles they need.
New bundles built by ci-deps-image:
- ubuntu-24.04-embedded: the membrowse ARM cross-toolchain (~0.5 GB), kept
out of -full so it does not bloat the interop workflows' pull.
- ubuntu-24.04-linuxkm: linux-headers-$(uname -r) + the kernel-module build
toolchain. linux-headers tracks the runner's running kernel, so a daily
job rebuilds it only when uname -r changed (recorded as an image label);
a mismatch during a runner-image rollout just falls back to apt.
Consumers now passing ghcr-debs-tag:
- sssd -> ubuntu-24.04-full (its deps added to that list)
- hostap-vm -> ubuntu-22.04-full (its deps added to that list)
- membrowse targets -> ubuntu-24.04-embedded; the two linuxkm targets ->
ubuntu-24.04-linuxkm (new per-target matrix.ghcr_tag)
- linuxkm.yml -> ubuntu-24.04-linuxkm (pinned to ubuntu-24.04 so the
bundle's headers match the runner kernel)
Each consumer still falls back to apt when its bundle is unavailable, so
nothing breaks until ci-deps-image first publishes the new tags.
The ci-cache-offload work added a ghcr .deb bundle path to
install-apt-deps, making the actions/cache apt-archive layer redundant.
Remove it so no apt-deps-* cache entries are produced. Apt packages now
install either offline from the ghcr bundle (when ghcr-debs-tag is set)
or via plain apt-get with the existing retry/backoff.
- Strip the Compute/Restore/Pre-seed/Collect/Save cache steps and the
cache-hit fast path; drop the now-unused 'cache' input.
- Update callers that passed 'cache': membrowse-onboard, membrowse-report
(and the apt_cache matrix key in membrowse-targets.json), and sssd.
The ghcr offline path and the ccache actions/cache usage are untouched.
