Hongming Wang 9df3159c59 feat(provisioner): pull workspace-template images from GHCR
Every standalone workspace-template repo now publishes to
ghcr.io/molecule-ai/workspace-template-<runtime>:latest via the
reusable publish-template-image workflow in molecule-ci (landed
today — one caller per template repo). This PR makes the
provisioner actually use those images:

- RuntimeImages map + DefaultImage switched from bare local tags
  (workspace-template:<runtime>) to their GHCR equivalents.
- New ensureImageLocal step before ContainerCreate: if the image
  isn't present locally, attempt `docker pull` and drain the
  progress stream to completion. Best-effort — if the pull fails
  (network, auth, rate limit) the subsequent ContainerCreate still
  surfaces the actionable "No such image" error, now with a
  GHCR-appropriate hint instead of the defunct
  `bash workspace/build-all.sh <runtime>` advice.
- runtimeTagFromImage now handles both forms: legacy
  `workspace-template:<runtime>` (local dev via build-all.sh /
  rebuild-runtime-images.sh) and the current GHCR shape. Keeps
  error hints sensible in both worlds.
- Tests cover the GHCR path for tag extraction and the new error
  message shape. Legacy local tags still recognised.

Local dev path unchanged — scripts/build-images.sh and
workspace/rebuild-runtime-images.sh still produce locally-tagged
`workspace-template:<runtime>` images, and Docker's image
resolver matches them before any pull is attempted. So
contributors can keep iterating on a template repo without
round-tripping through GHCR.

Follow-on impact:
- hongmingwang.moleculesai.app (and any other tenant EC2) will
  auto-pull `ghcr.io/molecule-ai/workspace-template-hermes:latest`
  on the next hermes workspace provision — picking up the real
  Nous hermes-agent behind the A2A bridge (template-hermes v2.1.0)
  without any tenant-side rebuild step.
