Demote per-book and per-chapter-list-page Info logs to Debug — these fire hundreds of times per catalogue run and drown out meaningful signals: - orchestrator: RunBook starting (per book) - metadata saved (per book) - chapter list fetched (per book) - scraping chapter list page N (per pagination page per book) The 'book scrape finished' summary log (with scraped/skipped/errors counters) remains at Info — it is the useful signal per book.
