Hongming Wang 7e3a6fd756 feat(canary): gate :latest tag promotion on canary verify green (Phase 3)
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.
