/**
 * A `fetch` that skips TLS certificate verification, for Node only.
 *
 * Node's built-in fetch ignores `https.Agent` and accepts only an undici
 * dispatcher, which Node does not expose without the `undici` package. Rather
 * than take a runtime dependency, this sends the request with `node:https`
 * and rebuilds a standard `Response`. It buffers the whole body, which suits
 * the SDK's JSON API calls, and otherwise follows native fetch: redirects are
 * followed per the Fetch standard, and a request with no socket activity for
 * `inactivityTimeoutMs` fails.
 *
 * Failures reject with `TypeError("fetch failed")` carrying the socket error as
 * `cause`, matching native fetch so error mapping treats both the same.
 *
 * @returns `undefined` when `node:https` is unavailable.
