[Enhancement] Add Lint Checks

[psriramsnc]

📋 Summary

This PR introduces a GitHub Actions workflow for linting and also fixes existing linting issues across the codebase.

🔧 Changes

• Added Lint workflow:
  • Runs on pushes to main
  • Runs on pull requests (excluding drafts)
  • Uses Poetry + cached virtualenv for dependencies
  • Runs make lint to enforce code style
• Fixed all existing linting errors in the repository to ensure the workflow passes from the start

✅ Benefits

• Ensures consistent coding style across all contributions
• Prevents new linting issues from entering main
• Clean baseline: no pre-existing lint errors
• Faster feedback cycle with cached Poetry environment

📌 Notes

• Developers should run make lint locally before pushing.
• Future lint errors will cause PR checks to fail until fixed.
