//! nats - NATS messaging system CLI
//!
//! The official NATS CLI for publishing, subscribing, managing
//! JetStream streams + consumers, replaying messages, and admin
//! operations against a NATS cluster. Pairs with `nats-server` for
//! local dev and `nsc` for credential management.
//!
//! ## Install paths
//! - macOS / Linux: Homebrew tap `nats-io/nats-tools/nats` (run
//!   `brew tap nats-io/nats-tools` once; jarvy does this implicitly).
//! - Windows: winget id `NATSAuthors.CLI` (verified against
//!   microsoft/winget-pkgs).

    // Linux: use Linuxbrew via the same tap rather than a distro
    // `natscli` package — verified that no Debian / RHEL family ships
    // a package by that name (security review F3).
