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- Remove outdated root-level documentation files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
