# Harness CI Keeper Plugin - Release Workflow
#
# HOW TO PUBLISH A NEW RELEASE:
# 1. Update the version in package.json (e.g., from 1.0.0 to 1.0.1)
# 2. Commit your changes: git commit -am "Bump version to 1.0.1"
# 3. Create a git tag matching the version: git tag v1.0.1
# 4. Push the tag to GitHub: git push origin v1.0.1
# 5. The workflow will automatically:
#    - Run linting
#    - Run tests
#    - Build the Docker image
#    - Generate SBOM
#    - Create a GitHub release
#
# Note: This workflow triggers on version tags (v*.*.*) or manual workflow dispatch
