- Fixed Jinja2 regex pattern to handle spaces around filters ({{ var | filter }})
- Added null safety in IS_CHANGED method for empty/None templates
- Restored dynamic output functionality for variable chaining
- Created 47 comprehensive tests with 78% coverage on format_string.py
- Set up test infrastructure with ComfyUI dependency mocking
- Used importlib to bypass package imports during testing
- Added conditional imports in root __init__.py for test compatibility
- Configured pytest in pyproject.toml (removed outdated pytest.ini)
- Added pytest and pytest-cov to dev dependencies
- Updated .gitignore for test artifacts
- Removed deprecated model_unload.py
