/**
 * Constructs the microsandbox sandbox backend: lightweight local VMs
 * via [microsandbox](https://www.npmjs.com/package/microsandbox) with
 * snapshot-backed templates and a firewall capable of domain-level
 * network policies and credential brokering.
 *
 * Supported hosts: macOS on Apple Silicon, or Linux (glibc) with KVM
 * enabled. The `microsandbox` package is not bundled with eve. When it
 * (or its VM runtime) is missing, `eve dev` installs both
 * automatically (disable with `setup: { autoInstall: false }`);
 * production processes fail with actionable errors instead.
 * Configuring this backend pins it unconditionally — when you want
 * fallback behavior, use `defaultBackend()` instead.
