/**
 * One-shot migration for the taxonomy change (Oct 2026):
 *
 * - Top-level groups introduced: Apps / Games / FinTech.
 * - Sub-category slugs renamed:
 *     wallets   → fintech
 *     utilities → productivity
 * - New sub-category under Apps:  browsers (for Theseus, Ariadne's Thread,
 *                                 Ariadne Navigator)
 * - Removed listing slug: ariadne-android (mislabel of ariadne-navigator)
 * - Renamed listing slug: ariadne-resolver-win → ariadne-thread-win
 *                         (to match the product's actual name,
 *                         Ariadne's Thread)
 *
 * This script deletes every row that was inserted by `seed.mjs` (identified by
 * signature='SM_OPERATOR_SEED'), so a subsequent `seed.mjs` run inserts the
 * fresh set with the new slugs + categories. Publisher-POSTed listings are
 * NOT touched — a listing with a real BIP-137 signature stays put, and the
 * admin can rewrite its category by withdrawing + republishing if needed.
 *
 * Run with:
 *   node scripts/migrate-taxonomy.mjs
 * or inside the VPS container:
 *   docker exec prometheus-prometheus-1 node scripts/migrate-taxonomy.mjs
 *
 * Idempotent — a second run finds no SM_OPERATOR_SEED rows and does nothing.
