feat(atlas): Phase C increment 1 — live CI runs on the pipeline
The CI stage now shows the pipeline's latest real execution, read live from the
in-cluster Gitea Actions API (public read, no token, gitea-http.gitea.svc):
"▶ run #N · <state>" coloured by outcome, prepended to the generated job list.
LatestRun + RunNode built test-first; cached in the same 30s liveOverlay; falls
back cleanly when Gitea is unreachable.

assessor-loop ledger / session_log deferred: no live CAD data exists for this repo
yet (brain confirms). Gitea run history is the real available trace.

Verified: build/vet/lint(0)/test green.
