/**
 * One-off, DB-free repair of the CURRENT data/products.json.
 *
 * The full rebuild (build-rwltd-data.js) reads the authoritative Kamatera
 * dw_unified over ssh, which is gated. This patcher applies the exact same
 * colorway-label repair (lib/relabel-colorways.js) to the snapshot already on
 * disk, so the fix ships without a prod-DB round-trip. build-rwltd-data.js also
 * runs the repair, so future rebuilds stay correct.
 *
 * Writes a timestamped .bak beside products.json first. $0 (local).
