[CI] Implement GitHub Actions workflow for automated Code Quality and Linting checks

[basantnema31]

Hello! I observed that there is no automated CI pipeline to run linters (like ESLint, Prettier, or Flake8 depending on the stack) on incoming Pull Requests. Having a CI workflow ensures that code quality remains high and prevents broken code from being merged into the main branch.

Closing this as it is an exact duplicate of Issue #362.
