Implement Code Linting in CI

[karademirmustafa]

Add a step in the CI pipeline to run a linter on the codebase. This ensures code quality and consistency.

Tasks:

• Choose a linter (e.g., ESLint for JavaScript/TypeScript, Pylint for Python).
• Integrate the linter into the GitHub Actions workflow.
• Configure the linter rules.
• Make the pipeline fail if linting errors are detected.
