/**
 * Migration — add the `notes` field to `raw_price_list`.
 *
 * The `file_name` field already exists in the live PB (added by the
 * operator via the admin UI). This script is idempotent: it checks
 * for the field first and only adds it if missing.
 *
 * The `notes` field carries free-text operator instructions for the AI
 * extraction step — e.g. "Brand is JEI. Apply 30% markup. All prices
 * in ZAR excl. VAT. POA for any missing values." The n8n workflow's
 * LLM user message is built from this + the supplier name.
 *
 * Run with:
 *   npm run pb:migrate:pricelist-notes
