//! Clap CLI surface (struct `Cli` + subcommands).
//!
//! Extracted from `main.rs` so xtask (and any future tool) can
//! reuse the command tree for man-page generation, completion
//! scripts, etc. Keep this file focused on the clap derive — all
//! dispatch / business logic stays in main.rs and the per-command
//! modules.
//!
//! Each subcommand is a tuple variant on [`Command`] delegating to
//! a `*Args` struct. The struct is the home for the rustdoc that
//! drives clap's `about` / `long_about` (first paragraph → about,
//! rest → long_about) and for `#[command(...)]` extras such as
//! `after_help`, aliases, and arg-group headings. Keep the variants
//! themselves bare — putting a doc comment on the variant would
//! shadow the struct's docs.
