Publish has been failing since the 2026-04-18 open-source restructure
(#964's merge) because workspace-server/Dockerfile still COPYs
./molecule-ai-plugin-github-app-auth/ but the restructure moved that
code out to its own repo. Every main merge since has produced a
"failed to compute cache key: /molecule-ai-plugin-github-app-auth:
not found" error — prod images haven't moved.
Fix: add an actions/checkout step that fetches the plugin repo into
the build context before docker build runs.
Private-repo safe: uses PLUGIN_REPO_PAT secret (fine-grained PAT with
Contents:Read on Molecule-AI/molecule-ai-plugin-github-app-auth).
Falls back to the default GITHUB_TOKEN if the plugin repo is public.
Ops: set repo secret PLUGIN_REPO_PAT before the next main merge, or
publish will fail with a 404 on the checkout step.
Also gitignores the cloned dir so local dev builds don't accidentally
commit it.

Completes the canary release train. Before this, publish-workspace-
server-image.yml pushed both :staging-<sha> and :latest on every
main merge — meaning the prod tenant fleet auto-pulled every image
immediately, before any post-deploy smoke test. A broken image
(think: this morning's E2E current_task drift, but shipped at 3am
instead of caught in CI) would have fanned out to every running
tenant within 5 min.
Now:
- publish workflow pushes :staging-<sha> ONLY
- canary tenants are configured to track :staging-<sha>; they pick
up the new image on their next auto-update cycle
- canary-verify.yml runs the smoke suite (Phase 2) after the sleep
- on green: a new promote-to-latest job uses crane to remotely
retag :staging-<sha> → :latest for both platform and tenant images
- prod tenants auto-update to the newly-retagged :latest within
their usual 5-min window
- on red: :latest stays frozen on prior good digest; prod is untouched
crane is pulled onto the runner (~4 MB, GitHub release) rather than
docker-daemon retag so the workflow doesn't need a privileged runner.
Rollback: if canary passed but something surfaces post-promotion,
operator runs "crane tag ghcr.io/molecule-ai/platform:<prior-good-sha>
latest" manually. A follow-up can wrap that in a Phase 4 admin
endpoint / script.

Default branch is now staging for both molecule-core and
molecule-controlplane. PRs target staging, CEO merges staging → main
to promote to production.
