//! Tests for the unified `Bash::exec_with_options` entry point.
//!
//! `exec_with_options` carries streaming + per-call extensions as fields of a
//! single `ExecOptions` request, and the older `exec*` methods are thin wrappers
//! over it. These tests pin that the request struct is wired through correctly.
