//! Tool system for kaish.
//!
//! Tools are the primary way to perform actions in kaish. Every command
//! is a tool — builtins and user-defined tools all implement
//! the same `Tool` trait.
//!
//! # Architecture
//!
//! ```text
//! ToolRegistry
//! ├── Builtins (echo, ls, cat, ...)
//! └── User Tools (defined via `tool` statements)
//! ```
