//! Rust-flavored building blocks for running AGNO-style agents.
//!
//! The crate provides a minimal runtime with:
//! - A language model abstraction (`LanguageModel`).
//! - A simple tool interface (`Tool` and `ToolRegistry`).
//! - An `Agent` that loops between the model and tools using structured JSON directives.
