//! Minimal BareLoop CLI — no tools, single-turn.
//!
//! Demonstrates the absolute simplest way to run a [`BareLoop`]:
//! create a mock client, build the loop, and call [`run`].

#![allow(clippy::expect_used, clippy::doc_markdown)]
//!
//! ```sh
//! cargo run --example hello-cli --features testing
//! ```
//!
//! [`run`]: loopctl::engine::bare::BareLoop::run
