smbcloud-cli 0.4.8

//! CI-aware interactive prompts.
//!
//! Thin wrappers over `dialoguer` that respect [`crate::ci::is_ci`]. In CI
//! (non-interactive) mode:
//!
//! * [`confirm`] resolves to its default instead of asking.
//! * [`input`] / [`input_optional`] return the supplied default, or fail.
//! * [`password`] and the required [`input_required`] fail fast — secrets and
//!   free-form answers can never be guessed.
//! * [`select`] / [`select_opt`] use an explicit CI default when the caller
//!   provides one, otherwise fail.
//!
//! Failures are plain [`anyhow::Error`]s with an actionable message, so a CI
//! pipeline gets a clear exit code instead of a hung TTY.
