fix: Resolve CI/CD workflow failures

- Add missing package-lock.json file for npm dependency caching
- Update actions/upload-artifact from deprecated v3 to v4
- Fixes workflow failures caused by missing lockfile and deprecated action

These issues were preventing the GitHub Actions from running properly.
