//! Newt-Agent inference layer.
//!
//! - `backend::InferenceBackend` is the trait every backend implements.
//! - `local::LocalOllamaBackend` and `local::LocalVllmBackend` are the only
//! backends compiled into the default Newt binary.
//! - `provider_plugin::ProviderPluginBackend` spawns a subprocess that
//! speaks the Newt-Provider JSON-RPC protocol — this is how OpenAI,
//! Anthropic, etc. join via opt-in plugin installs.
