1//! Quantum circuit formatter with `SciRS2` code analysis for consistent code style
2//!
3//! This module provides comprehensive code formatting for quantum circuits,
4//! including automatic layout optimization, style enforcement, code organization,
5//! and intelligent formatting using `SciRS2`'s graph analysis and pattern recognition.
