Note

Low Risk
Test-only refactor and devDependency cleanup; production code paths are unchanged.

Overview
Removes the sinon devDependency from @metamask/composable-controller (and the corresponding yarn.lock entry).

Updates ComposableController.test.ts to replace sinon.stub() usage with jest.fn() and switches assertions to Jest call tracking, eliminating the sinon.restore() cleanup hook.
