 * Construct a mock {@link DeviceExchangeError} for tests.

 * The DMK `DeviceExchangeError` is normally raised inside the DMK runtime;
 * tests need a structurally-equivalent value without going through DMK.
 * This helper centralises the cast so test files don't each roll their own.
 *
 * @param errorCode - The hex error code to embed (e.g. `'6985'`).
 * @returns A mock `DeviceExchangeError<TErrorCode>`.
