cleanup: move remaining JavaScript development artifacts to history

Complete the cleanup by moving the final 6 JavaScript development files
(4 debug tools + 2 demo HTML pages) to history archive.

Additional Files Moved:
- debug_buttons.js: Button functionality debugging tool
- debug_floating_menu.js: Floating menu structure inspection
- e2e_tests.js: End-to-end test runner with custom framework
- final_functionality_verification.js: Final verification script
- demo_clean_editor.html: Clean section editor demonstration
- test_dom_integration.html: DOM integration testing page

Documentation Updates:
- Updated history/javascript-dev-tests/README.md to document all 59 archived files
- Added categorization for debug tools and demo pages
- Complete project root directory cleanup achieved

Project Status:
- ✅ Main directory now clean of all development artifacts
- ✅ All 59 JavaScript development files properly archived
- ✅ Comprehensive documentation of archived functionality
- ✅ 79 automated tests providing equivalent coverage
