Walkthrough

The test setup file was simplified by removing imports of TextEncoder and TextDecoder from node:util and eliminating the associated workaround code that previously mapped these to global objects. The removal includes ts-expect-error comments that were part of this polyfill approach. The logger mock setup functionality remains intact with no changes to test behavior.
