Issues:

• 8 top-level folders + 9 files = cluttered root
• Not immediately clear which folders are for which implementation
• Shared resources mixed at root level

Benefits:

• ✅ 3 top-level folders + documentation files = clean root
• ✅ Clear purpose: development/ vs production/ vs shared/
• ✅ Better organization: All shared resources in one place
• ✅ Easier navigation: Developers know exactly where to look
• ✅ Consistent naming: Matches the project's description of TypeScript for development and C++ for production

Migration Summary

Folder Renames

• dbal/ts/ → dbal/development/
• dbal/cpp/ → dbal/production/

Consolidated into shared/

• dbal/api/ → dbal/shared/api/
• dbal/backends/ → dbal/shared/backends/
• dbal/common/ → dbal/shared/common/
• dbal/tools/ → dbal/shared/tools/
• dbal/scripts/ → dbal/shared/scripts/
• dbal/docs/ → dbal/shared/docs/

Files Reorganized

• Historical implementation docs moved to shared/docs/
• Core documentation remains at root
• Each implementation has its own .gitignore

References Updated

• 80+ files updated across entire project
• 0 old references remaining
• All workflows, documentation, and code updated
