Enhance Repository Cleanliness by Updating .gitignore

[MohAnghabo]

Greetings Team,

During my recent contributions to our project, I observed that certain system-generated files and directories are not presently accounted for in our .gitignore file. These entries are typically auto-generated by development tools and operating systems, and their exclusion from our repository is essential to maintain its cleanliness and organization.

I recommend we include the following items in the .gitignore:

• .vscode/ - Created by Visual Studio Code, this directory holds IDE-specific settings that are personal and not necessary for the collective project.
• .idea/ - Similar to the above, this directory is produced by JetBrains IDEs and contains user-specific configurations that should be excluded from the repository.
• .obsidian/ - Generated by the Obsidian note-taking app, this directory includes user-specific settings and cache, which are irrelevant to the project.

I invite everyone to share their input on this proposal. Pending no significant objections, I am prepared to implement these updates.
