/**
 * Auto-refresh transport middleware.
 *
 * Integrates `AutoRefreshCoordinator` at the transport boundary so that ALL
 * typed operator/peer SDK calls benefit from automatic token refresh, not only
 * `auth.current()`.
 *
 * Responsibilities:
 *   1. Pre-flight: call `coordinator.ensureFreshToken()` before dispatching the
 *      request. Updates `ctx.headers.Authorization` with the fresh token so
 *      consumer middleware (which runs after this one) sees the current token.
 *   2. Reactive 401: if `next()` throws a 401-shaped error, trigger a refresh
 *      via `coordinator.refreshAndRetryOnce()` and set `ctx.response` to the
 *      retry result so the transport can return it to the caller.
 *   3. Loop prevention: retry requests carry `__gv_ar_attempted: true` in their
 *      options. The middleware recognises this flag and passes through without
 *      additional refresh logic, preventing infinite recursion.
 *   4. Error passthrough: terminal auth errors from the coordinator are placed
 *      directly onto `ctx.error` rather than thrown, so the transport's
 *      middleware-error-wrapping instrumentation does not re-wrap them as
 *      `kind:'unknown'`.

/**
 * Create a transport middleware that integrates the `AutoRefreshCoordinator`
 * into every HTTP request.
 *
 * @param coordinator - The auto-refresh coordinator managing token lifecycle.
 * @param transport   - The HTTP JSON transport used to re-issue the request on
 *                      reactive 401 retry. Must be the same transport instance
 *                      whose middleware chain contains this middleware, so that
 *                      the retry benefits from other middleware (e.g. logging,
 *                      tracing) except for another auto-refresh cycle.
 * @param tokenStore  - The token store from which to read the fresh token after
 *                      pre-flight refresh, so `ctx.headers.Authorization` can
 *                      be updated before consumer middleware runs.
 *
 * @example
 * const mw = createAutoRefreshMiddleware(coordinator, transport, tokenStore);
 * transport.use(mw);
