/**
 * @fileoverview Code tracing strategy for identifying unused code with high confidence.
 *
 * This strategy uses a multi-pass approach to trace code paths and identify unused code:
 * 1. Maps entry points and dependencies
 * 2. Traces references through the codebase
 * 3. Verifies findings and assesses confidence
 *
 * It collects detailed evidence for each identified unused element to ensure high confidence
 * in recommendations for removal.
