Write the structural-triage suggestions to Talk/<stem>.md in the Lucien
<<<TALK>>> style. Writes ONLY under Talk/ — it NEVER edits an article, so
a cross-article split/merge is surfaced, never silently performed. Returns the
written path, or null when there is nothing to suggest. The block is rewritten
each run (idempotent — one managed block per article).
