//! `harn local` — first-class local LLM runtime lifecycle commands.
//!
//! Tracks issue #1599. Wraps Ollama, llama.cpp, MLX, and other
//! OpenAI-compatible local servers behind a stable command surface while
//! the underlying CLIs keep churning. Subcommands:
//!
//! - `list`   — survey every local provider Harn knows about
//! - `status` — show the active selection plus a brief summary of all
//! - `switch` — make a model the active local runtime (warm + persist)
//! - `stop`   — unload loaded models / stop Harn-managed servers
//!
//! All state lives under `<state_root>/local/` (see `super::local::state`).
