Subject: [PATCH] Add test cases for `validateRowIds`

- Added test cases in `tests/unit/sql-utils.test.ts` to ensure `validateRowIds` properly rejects non-array inputs like `null`, `undefined`, empty objects, and primitive numbers, checking that iteration fails robustness tests and accurately triggers a `TypeError`.
