Assert instance identity for pass-through inputs.

toEqual accepts a newly constructed but structurally equal Index or CheckConstraint. It does not verify the pass-through contract. Add toBe assertions for the constructed elements.

Proposed test update 
     expect(result.indexes).toEqual([idx]);
+    expect(result.indexes[0]).toBe(idx);
...
     expect(result.checks).toEqual([check]);
+    expect(result.checks?.[0]).toBe(check);

In `@packages/2-sql/1-core/contract/test/entity-kinds.test.ts` at line 125, Update
the assertions in the affected entity-kind tests to use toBe for the constructed
Index and CheckConstraint elements, verifying the returned values preserve
object identity for pass-through inputs rather than only structural equality.
