chore(ci): regenerate stale catalogs and re-record translation pairs

- gen-cordis-catalog / gen-persistence-catalog / gen-doc-graphs after the
  error-reason and steering/message changes (line anchors and event
  producer/consumer graph drifted).
- verify-translation-pairing --write --all: every bilingual pair touched
  by the PR (agent notes, session/core docs, READMEs) plus the merge.
- queue-actions preserved golden re-recorded against the rebuilt client
  (branch disabled on non-completed-turn tails is back in effect).
