Ryan Malloy 572379d9aa 🎉 Complete Phase 2: WordPerfect processor implementation
 WordPerfect Production Support:
- Comprehensive WordPerfect processor with 5-layer fallback chain
- Support for WP 4.2, 5.0-5.1, 6.0+ (.wpd, .wp, .wp5, .wp6)
- libwpd integration (wpd2text, wpd2html, wpd2raw)
- Binary strings extraction and emergency parsing
- Password detection and encoding intelligence
- Document structure analysis and integrity checking

🏗️ Infrastructure Enhancements:
- Created comprehensive CLAUDE.md development guide
- Updated implementation status documentation
- Added WordPerfect processor test suite
- Enhanced format detection with WP magic signatures
- Production-ready with graceful dependency handling

📊 Project Status:
- 2/4 core processors complete (dBASE + WordPerfect)
- 25+ legacy format detection engine operational
- Phase 2 complete: Ready for Lotus 1-2-3 implementation
