testing/cross_backend/bootstrap_backend.ts

One-call spawn + bootstrap helper.
Composes spawn_backend(config) and bootstrap({transport, config}) so a
consumer's vitest globalSetup reduces to a single await:
import {bootstrap_backend} from '@fuzdev/fuz_app/testing/cross_backend/bootstrap_backend.js';

export default async function ({provide}) {
  const bootstrapped = await bootstrap_backend(deno_backend_config());
  provide('backend_handle', bootstrapped);
  return async () => {
    await bootstrapped.teardown();
  };
}If bootstrap() throws — typically a bad token, port collision, or
keeper-username mismatch — the spawned binary is torn down before the
error propagates so vitest doesn't strand the port.

(config: BackendConfig): Promise<BootstrappedBackendHandle>

Spawn the test binary described by config, bootstrap a keeper, and
return the enriched handle.
The keeper transport is constructed against config.base_url with no
initial cookies; bootstrap() populates its jar with the session
cookie returned by POST {config.bootstrap_path}. Subsequent calls
against bootstrapped.keeper_transport are authenticated as keeper.
Mirrors the composition default_cross_process_setup's caller would
otherwise hand-roll in every consumer's globalSetup.
