//! Clap-derive dispatcher for `greentic-deployer op …` (`A3`).

//! Owns the `OpCommand` clap tree + the `dispatch_op` entry point. The
//! actual per-noun command logic lives in `cli::env`/`cli::env_packs`/etc;
//! this module is the wiring layer that converts argv → typed payloads →
//! library calls and prints the JSON envelope to stdout.
