When child_process.spawn receives a command that cannot be resolved, the call can return a ChildProcess before the failure is delivered. Attach an error listener immediately and handle error code ENOENT; do not rely only on synchronous exceptions or the close event.
Problem details
- Observed symptom
- The spawn call returned a ChildProcess, then emitted exactly one error with code ENOENT.
- Context

Handle spawn failures through the error event
Register an error listener immediately after spawning so command-resolution failures are observed before relying on later lifecycle events.
