Remove node_modules from repo and add to .gitignore to stop tracking unwanted dependencies

#154 issue fix

Related Issue

None - this is a cleanup update to follow best practices.

Description

This PR removes the node_modules/ directory from version control and adds it to the .gitignore file.

Since node_modules only contains third-party packages that can be reinstalled with npm install or yarn install, there’s no need to keep them in the repo.
Removing them helps reduce clutter, keeps the repository lightweight, and follows standard practices for Node.js projects.
