shellist 0.1.0

//! Shell history analysis. Parses `.bash_history`, counts commands, and ranks by frequency.
//!
//! ```rust
//! let ranked = shellist::analyze("ls\ngit\nls\ncd\ngit\nls");
//! assert_eq!(ranked, vec![
//!     ("ls".to_string(), 3),
//!     ("git".to_string(), 2),
//!     ("cd".to_string(), 1),
//! ]);
//! ```
