Description

This pull request includes the following changes:

1. Addition of the /.idea folder to .gitignore:

   • This change prevents files related to IDE configuration from being unintentionally committed.

2. Namespace adjustments in test classes:

   • Updated the namespaces of certain test classes to accurately reflect the directory structure they reside in, ensuring consistency and alignment with PSR-4 standards.

3. Changelog update for version 1.1.4:

   • Added an entry for version 1.1.4 in the CHANGELOG.md file to document the recent updates and improvements made to the project.

Motivation

• The inclusion of /.idea in .gitignore supports developers by excluding IDE-specific configuration files from the repository, avoiding unnecessary clutter in version control.
• Aligning test namespaces with the directory structure improves maintainability and clarity for future contributors.
• Keeping the changelog updated ensures that users and contributors have a clear view of the project's progress and changes.

Checklist

• Reviewed contribution guidelines.
• Verified that the .idea folder is excluded correctly in .gitignore.
• Confirmed that all tests pass with updated namespaces.
• Added relevant details to the changelog.

Additional Notes

I believe these changes align with the project's standards and contribute to maintaining a positive development environment. Feedback is welcome and appreciated!
