AI Summary: This issue addresses an inconsistency in documentation where database directory names were referenced with incorrect casing (e.g., `Factories` instead of `factories`). The fix involves updating several documentation files, including a new convention document, to reflect the correct lowercase naming convention for `factories`, `migrations`, and `seeders` directories. This is a documentation-only change with no breaking changes or code modifications.
