feat(boot): surface pre-published probe replay on landing page

- boot loads the completed run from /api/artifacts/manifest and renders its
  latest checkpoint with concrete build-review labels (no fake unknown-state
  wording); offline fallback still shows the honest placeholder
- artifact manifest/steps endpoints now fall back to disk when a completed
  run has no in-memory registry entry, keeping pre-published history browsable
  after a service restart (digest-verified, .glb-only / steps/ / logs/ rejected)
- driver: heritage flows pin heritage ids explicitly; new checks for the
  boot probe replay and its labels; 72/72 green with zero console errors
