/**
 * Migration — add `source_file` (text) to `price_list`.
 *
 * Stores the `raw_price_list.id` that an extracted line item came
 * from. Used by the n8n workflow's verification step:
 *
 *   // After the POST loop
 *   const actual = await pb.collection('price_list').getList(1, expected, {
 *     filter: `source_file = "${rawId}"`,
 *   });
 *   if (actual.items.length === expected) {
 *     // safe to PATCH raw_price_list.status = "Completed"
 *   } else {
 *     // PATCH Failed with "X/Y items created"
 *   }
 *
 * Also useful for the agent at quote time: "give me the full price
 * list for the file this row was sourced from."
 *
 * Idempotent: re-runs are safe.
 *
 * Run with:
 *   npm run pb:migrate:price-list-source-file
