Add GitHub Actions workflow for release automation

Introduces a workflow to automate release creation on pushes to the main branch. The workflow extracts the version from conf.yml, builds the project using blueprint-export, creates a GitHub release with installation instructions, and uploads the generated binary as a release asset.
