// Regression: the shared interactive prompt helper (createPrompt) used rl.question
// without an EOF guard, so a non-interactive stdin (pipe, CI, `< /dev/null`) left
// the promise pending — Node then warned about an "unsettled top-level await" at
// exit and the command hung. ask/askSecret now resolve on the readline `close`
// event (fired on EOF) with the default / empty string instead of hanging. close()
// here simulates that EOF/non-interactive close.
