* up

* fix

* modula rpipeline update: filter out none for input_names, fix default blocks for pipe.init() and allow user pass additional kwargs_type in a dict

* qwen modular refactor, unpack before decode

* update mellon node config, adding* to required_inputs and required_model_inputs

* modularpipeline.from_pretrained: error out if no config found

* add a component_names property to modular blocks to be consistent!

* flux image_encoder -> vae_encoder

* controlnet_bundle

* refator MellonNodeConfig MellonPipelineConfig
