+/**
+ * POS-002 — Add `store_id` to `inventory_stock` and `inventory_movements`.
+ *
+ * Steps in `up()`:
+ *   1. Add `store_id` as a NULLABLE column (so the backfill doesn't fail).
+ *   2. Backfill every existing row with the well-known default store UUID.
+ *   3. Make `store_id` NOT NULL and add the FK to `pos_stores`.
+ *   4. Drop the old single-column unique constraint on `inventory_stock.variant_id`.
+ *   5. Add the new composite unique constraint `(variant_id, store_id)`.
+ *   6. Mirror the same 5-step pattern for `inventory_movements` (without the
+ *      unique constraint, since movements don't have a UNIQUE invariant).
+ *
+ * Idempotent: every ALTER uses `IF NOT EXISTS` / `IF EXISTS` / `DO` blocks
+ * so re-running is a no-op.
+ *
+ * @param {import('node-pg-migrate').MigrationBuilder} pgm
