braillify 2.0.1

//! Rule system for Braille encoding.
//!
//! Each rule is an independent module that implements a specific article
//! of the 2024 Korean Braille Standard (개정 한국 점자 규정).
//!
//! Rules are independently testable and traceable.
//!
//! # Architecture
//!
//! - [`traits::BrailleRule`] — the plugin interface every rule implements
//! - [`engine::RuleEngine`] — the host that registers, sorts, and applies rules
//! - [`context::RuleContext`] — shared state + current position passed to each rule
//!
//! ```ignore
//! let mut engine = RuleEngine::new();
//! engine.register(Box::new(korean::rule_11::Rule11));
//! engine.register(Box::new(korean::rule_12::Rule12));
//! engine.disable("12"); // disable a specific rule
//! engine.apply(&mut ctx)?;  // apply all enabled rules
//! ```
