style: Run black formatter on 16 files

Applied black formatting to files modified in linting fixes:

Source files (8):
- config_extractor.py
- doc_scraper.py
- how_to_guide_builder.py
- llms_txt_downloader.py
- llms_txt_parser.py
- pattern_recognizer.py
- test_example_extractor.py
- unified_codebase_analyzer.py

Test files (8):
- test_architecture_scenarios.py
- test_async_scraping.py
- test_github_scraper.py
- test_guide_enhancer.py
- test_install_agent.py
- test_issue_219_e2e.py
- test_llms_txt_downloader.py
- test_skip_llms_txt.py

All formatting issues resolved.
