Summary of Changes

Hello @Paulchen5, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request aims to standardize the development environment for VS Code users by introducing recommended extensions and enforcing consistent code formatting rules. This helps ensure a unified code style across the project and improves developer experience by automating common formatting tasks.

Highlights

• VS Code Extension Recommendation: I've added a new .vscode/extensions.json file to recommend the charliermarsh.ruff extension. This helps ensure developers use a consistent linter and formatter for Python code within the workspace.
• Standardized Formatting Settings: I've updated .vscode/settings.json to enforce consistent code style. Specifically, I've set files.insertFinalNewline: true, files.trimFinalNewlines: false, and files.trimTrailingWhitespace: false. Additionally, I've added editor.rulers: [80] to provide a visual guide for line length.
• Minor Setting Reformatting: I've also made a minor readability improvement to the python.testing.pytestArgs setting in .vscode/settings.json, reformatting it to a multi-line array.
