nomoreide-cli 0.12.0

//! `nomoreide agents [status|doctor|read]` — the Rust half of
//! `src/cli/agents.ts`.
//!
//! Read-only by construction. Everything here reports what an agent's config
//! already says; the surface that *writes* one is `nomoreide profile apply`,
//! which is a different command for the same reason `git-actions` is a
//! different module from `git-manager`.
