/**
 * Repair for the 2026-10-27 --delete-dropped run: the RENAME_MAP entries
 * 'Government' -> 'Government & Agencies' and 'Education' -> 'Education
 * Communications' are NOT idempotent (the old names double as the NEW main
 * market names). The re-run therefore renamed the MAIN records (#50/#20,
 * stories and teaser travelled along), created fresh empty "Government" /
 * "Education" records, and pass 4 deleted the original (empty) sub-market
 * records as unclaimed.
 *
 * This script swaps everything back:
 *   - #<main> "Government & Agencies"  -> title Government, slug government,
 *     detail_page = page /markets/government
 *   - the empty record titled "Government" (created today) -> title
 *     Government & Agencies, slug government-agencies, detail_page =
 *     page /markets/government/government-and-agencies
 *   - same pair for Education / Education Communications
 *
 * Plain PDO (pattern migrations/check_bg.php). Dry-run by default.
 *
 * Usage:  php migrations/fix_market_rename_regression.php [--apply]
