/**
 * Group active pages by slugified title and return only the groups
 * with more than one member. `null`/empty titles are skipped (those
 * pages surface as "invalid" elsewhere). Archived / trashed pages
 * never participate.
 *
 * Slugs are the primary identifier on the local machine; two Notion
 * pages slugifying to the same string is unambiguously a problem.
 * sync skips them with a warning, install refuses them, doctor
 * surfaces them so the user can rename one in Notion.
