- Create AuthHeaderProvider that integrates with Firebase and API key stores
- Add core extension to register auth provider during preInit
- Implement automatic auth header injection for all HTTP requests
- Add comprehensive unit and integration tests
- Include examples showing migration from manual to automatic auth
This completes the header registration system by connecting it to the
actual authentication mechanisms in ComfyUI.
