fix: catch unhandled promise rejection in non-interactive CLI path

runNonInteractive() is async but was called fire-and-forget. If an
unexpected error escapes the internal try/catch, Node.js would emit
an unhandled rejection instead of clean JSON. Add .catch() to ensure
errors always produce valid JSON output with exit code 1.
