//! `arc run` — run a compiled application command by name.
//!
//! Distinct from `arc s` (which runs application-owned project scripts): `arc
//! run` executes a compiled Rust command registered via `#[command(...)]`
//! and the application's `CommandRegistry`. The CLI shells out to the app
//! binary with `--run-command <name>` and forwards any trailing arguments;
//! the application decides how to interpret them (PROGRAM.md §"Typed Rust
//! application commands").
