This commit reorganizes the `/workflows` directory to improve clarity. The folder
now contains only the workflows that utilize GGUF format checkpoints, while SAFETENSORS
versions of these workflows are relocated to a subdirectory named "safetensors_versions".
Additionally, a "development" subfolder is created for storing workflow files
used during testing and development. The directory's readme file has been
renamed to "README.md" for consistency.
