docs: consolidate and restructure documentation architecture
- Remove outdated root-level documentation files - Delete IMPLEMENTATION_STATUS.md, WORK_IN_PROGRESS.md, UI_IMPROVEMENTS_SUMMARY.md, CLAUDE.md - Reorganize documentation into docs/ folder - Move UNIFIED_EDITOR_EXPERIENCES.md → docs/unified-editor-experiences.md - Move DATATABLE_MIGRATION_PROGRESS.md → docs/datatable-migration-progress.md - Move SEED_SCRIPT_README.md → docs/seed-script-readme.md - Create comprehensive new documentation - Add docs/implementation-status.md with production readiness assessment - Add docs/work-in-progress.md with active development tracking - Add docs/development-achievements.md consolidating all major accomplishments - Update documentation hub - Enhance docs/README.md with complete 13-document structure - Organize into logical categories: Core, Status, Achievements - Provide clear navigation and purpose for each document Features: - 73% code reduction achievement through unified editor experiences - Complete DataTable migration with enterprise features - Comprehensive seed database with realistic research scenarios - Production-ready status with 100% backend, 95% frontend completion - Clean documentation architecture supporting future development Breaking Changes: None - documentation restructuring only Migration: Documentation moved to docs/ folder, no code changes required
