docs: reorganize markdown documentation into proper directory structure

Move technical documentation from root directory to organized locations
for better project structure and discoverability.

Documentation Moved to docs/development/:
- UserInterfaceFramework.md: UI component framework specification and architecture
- LOST_FUNCTIONALITY_ANALYSIS.md: Technical analysis of recovered JavaScript functionality
- TDD_COMPLIANCE_REPORT.md: Test-Driven Development methodology validation report

Obsolete Documentation Archived:
- TEST_ENVIRONMENT.md → history/javascript-dev-tests/
  Manual testing environment docs (replaced by automated testing)

Files Remaining in Root:
- CHANGELOG.md: Project changelog (standard location)
- TODO.md: Active project tasks (operational file)

Benefits:
- ✅ Clean root directory with only operational files
- ✅ Technical documentation properly organized in docs/development/
- ✅ Obsolete docs archived with historical context
- ✅ Improved project navigation and documentation discoverability
- ✅ Follows standard project organization conventions

Project Structure:
- Root: Operational files (CHANGELOG, TODO)
- docs/development/: Technical documentation and reports
- history/: Archived development artifacts and obsolete documentation
