/**
 * Flattens a thrown error into the plain `{ returnCode, errorMessage }` value this SDK
 * has always resolved to.
 *
 * `processErrorResponse` returned a plain object through `@zondax/ledger-js` 0.2.x. At
 * 2.0.0 it returns a `ResponseError`, which is an `Error` subclass, and the difference is
 * observable in two ways that reach callers:
 *
 * - `structuredClone` keeps only an Error's `name` / `message` / `stack`, so `returnCode`
 *   and `errorMessage` come back `undefined`. That is the algorithm behind `postMessage`,
 *   web workers and Electron IPC -- all of which sit between this SDK and a UI in practice.
 * - `resp instanceof Error` is a common stand-in for "this threw". An error returned as a
 *   *value* would now answer yes to it.
 *
 * Every rejection path in this package routes through here so neither changes.
