Proposed Workflow Enhancements

1. Documentation Update Check:

   • Add a new job in the workflow to detect changes in .md files or the docs/ directory.
   • The job should fail if no documentation changes are found when code changes require corresponding updates.

2. Lint and Formatting:

   • Introduce a job to verify code formatting using gofmt or a similar tool, ensuring consistent style across the project.
   • Enhance the existing linting job by:
     • Installing and running golangci-lint to detect issues.
     • Using reviewdog for inline annotations in pull requests, improving error visibility and feedback.

Both enhancements should be integrated as prerequisites for other jobs like testing and building.
