//! # Binary Utility Module
//!
//! This module provides utility functions for locating and verifying the `stackql` binary.
//! It supports checking the binary's presence in the system `PATH` or the current directory
//! and retrieving the full path to the binary if it exists.
//!
//! ## Features
//! - Checks if the `stackql` binary is available in the system's `PATH`.
//! - Retrieves the full path of the `stackql` binary from the current directory or `PATH`.
//!
//! ## Example Usage
//! ```rust
//! use crate::utils::binary::{binary_exists_in_path, get_binary_path};
//!
//! if binary_exists_in_path() {
//!     if let Some(path) = get_binary_path() {
//!         println!("Found stackql binary at: {:?}", path);
//!     }
//! }
//! ```
