Introduces a release workflow that triggers on pushes to main. The workflow extracts the version from pyproject.toml, ensures unique version tags, and creates a GitHub release using softprops/action-gh-release.
Converted the publish workflow from a job-based GitHub Actions workflow to a reusable composite action. Added inputs for personal access token and skip_checkout, included Python setup and comfy-cli installation steps, and updated the publish command to use the new structure.
