//! `feira` — CLI for the caixa tatara-lisp package system.
//!
//! The name (Portuguese for *market/fair*) mirrors Rust's `cargo`: the
//! marketplace where caixas are authored, resolved, published, and consumed.
//!
//! Phase 1 scope:
//! - `feira init <nome>` — scaffold a new caixa
//! - `feira add <nome>` — append a dep to caixa.lisp
//! - `feira lock` — resolve deps + write lacre.lisp
//! - `feira build` — validate layout + parse every `:bibliotecas`
//! - `feira nix` — emit a flake.nix for the caixa
