PR Summary

• Update to .gitattributes File
  In an effort to enhance the development process, changes were made to the .gitattributes file. The system will no longer track changes to the /phpstan.neon file, which helps to reduce clutter in the project history. More importantly, the /phpstan.neon.dist file has been added for export. This allows the whole sequence of operations, rules, and configurations contained within the file to be reused in different environments or platforms seamlessly. This fosters reusability and consistency across the development process.
