simplify

Remove the --experimental flag requirement for creating image generation
models. Now ollama create automatically detects imagegen models by checking
for model_index.json in the model directory and routes them to the direct
creation path.

This simplifies the workflow for creating FLUX and other diffusion models -
users no longer need to pass --experimental.
