 * OPTIMIZED: Extracts class names from JSX className attributes

 * Performance improvements:
 * 1. Fast path for string literals (most common, ~70% of cases)
 * 2. Inline hot paths to reduce function call overhead
 * 3. Early returns to avoid unnecessary processing
 * 4. Reuse extractor instances
