- Introduced dependabot configuration for Go modules and GitHub Actions.
- Added linting workflow to enforce code quality on pushes and pull requests.
- Created release workflow to automate versioning and releases based on tags.
- Implemented testing workflow to run tests across multiple Go versions and OS environments.
