+/**
+ * One-shot bulk action: drop the seed demo KCN rows and publish every
+ * OSM-imported KCN to the public catalog.
+ *
+ *   Usage:
+ *     NODE_OPTIONS="-r dotenv/config" DOTENV_CONFIG_PATH=.env \
+ *       pnpm tsx scripts/promote-all-osm.ts [--dry-run] [--keep-manual]
+ *
+ *   Flags:
+ *     --dry-run       Show what would change, don't write.
+ *     --keep-manual   Skip the seed-row deletion step (only promote OSM).
+ *
+ * What it does:
+ *   1. Optionally `DELETE FROM IndustrialPark WHERE dataSource = 'MANUAL'`
+ *      (cascade drops any IndustrialListing rows pointing at them via FK).
+ *   2. `UPDATE IndustrialPark SET dataSource = 'OSM_PROMOTED', isPublic = true
+ *      WHERE dataSource = 'OSM'` — every row goes public in one shot.
+ *
+ * Safe to re-run: idempotent on the OSM side (already-promoted rows are
+ * skipped by the WHERE clause). Manual deletion is also safe — once they're
+ * gone, subsequent runs find nothing to delete.
