Phase 6 Achievements:
- Deleted 62 duplicate TSX files with JSON equivalents (44 atoms + 14 molecules + 4 organisms)
- Added 27 missing component exports to json-components.ts
- Created interface files for deleted components in src/lib/json-ui/interfaces/
- Copied JSON definitions from config/pages to components/json-definitions/ for consistency
- Updated atoms/index.ts with comprehensive exports for all 100+ components
- Fixed import issues in AtomicComponentDemo.tsx
- Removed orphaned CodeEditor registry entry and JSON config file
- Fixed registry entry count (359 total, 0 orphans, 0 duplicates)
