 *
 * <p>Duplicate host configurations allow administrators to define hostname patterns
 * that should be treated as equivalent during crawling. This helps avoid indexing
 * duplicate content from the same logical site that may be accessible via different
 * hostnames (e.g., www.example.com and example.com).</p>

- **Factory**: `CrawlerClientFactory`, `ExtractorFactory` - protocol/format-specific component selection
- **Strategy**: `CrawlerClient`, `Extractor`, `Transformer` - pluggable implementations
