1//! Quantum circuit linter using `SciRS2` pattern matching for code quality analysis
2//!
3//! This module provides comprehensive code quality analysis for quantum circuits,
4//! including pattern detection, anti-pattern identification, optimization suggestions,
5//! style checking, and best practice enforcement using `SciRS2`'s advanced pattern
6//! matching and graph analysis capabilities.
