- Add registry metadata: name 'saturnnodes', license file, requires-python, classifiers, Bug Tracker/Documentation URLs, requires-comfyui, optional extras.
- Add 400x400 Saturn icon (web/logo.png) replacing the previous 404 Icon URL.
- Add .comfyignore manifest and publish_action.yml workflow (needs REGISTRY_ACCESS_TOKEN secret).
- release.yml now publishes curated CHANGELOG notes instead of raw auto-generated compare links.
- lint.yml now runs on all branches like the test suite.
- Remove install.py: dependencies are declared in pyproject.toml / requirements.txt only.
- Bump version to 2.6.1 (registry versions are immutable once published).
