// Toyota Way: Unified Detection Framework for Structural Complexity Reduction
//
// This module consolidates detection services under a single, unified
// framework to reduce structural complexity and achieve A+ grade.
//
// Consolidates:
// - duplicate_detector.rs (high-performance LSH duplicate detection)
// - satd_detector.rs (Self-Admitted Technical Debt detection)
// - polyglot_analyzer.rs (cross-language analysis)
