shipper-cli 0.3.0-rc.2

//! # shipper-cli
//!
//! Real CLI adapter for Shipper (#95 three-crate split).
//!
//! This crate owns the command-line surface: argument parsing
//! (`clap`), subcommand dispatch, help text, progress rendering. It
//! depends on [`shipper_core`] for the actual engine.
//!
//! ## Architecture
//!
//! ```text
//! shipper (install façade) -> shipper-cli (this crate) -> shipper-core (engine)
//! ```
//!
//! The `shipper` binary on crates.io is a three-line wrapper that
//! calls [`run`]; a separate `shipper-cli` binary exists in this
//! crate for backward compatibility with `cargo install shipper-cli`
//! and for workspace-local development.
//!
//! ## Embedding
//!
//! Most callers should use the `shipper` CLI directly. If you need to
//! embed the exact CLI surface in another Rust program — for example,
//! a wrapper that invokes `shipper` with extra preflight steps — call
//! [`run`]. For programmatic use without a `clap` dependency, depend
//! on [`shipper_core`](https://crates.io/crates/shipper-core) instead.
