This commit introduces a new utility function, `toId`, to handle ID conversions in the `listingvarient.schema.js` file. The `recalculate` method is updated to compute and update the stock quantity for listing variants based on product SKU and stock location. Additionally, a new test case is added in `stockQuantity.recalculate.test.js` to verify the correct behavior of stock quantity calculations before rolling up, ensuring comprehensive test coverage for this functionality.
