 * OPTIMIZED: Service responsible for orchestrating class name extraction
 *
 * Performance improvements:
 * 1. Fast path for JSX elements (skip non-JSX nodes early)
 * 2. Fast path for tv() calls (check only call expressions)
 * 3. Fast path for cva() calls (check only call expressions)
 * 4. Single extractor instance (avoid canHandle() overhead)
 * 5. Direct node type checking (faster than polymorphic calls)
 * 6. Reduced function call overhead
 * 7. Conditional extractor execution (skip disabled extractors)
