Cortex version

v70

Describe the Bug

1. cortex pull https://huggingface.co/cortexso/NONEXISTENT_MODEL
2. Get "model downloaded successfully"
3. Get "not a valid GGUF file"
4. run ls /cortexcpp/models
5. See that a model folder was created for "nonexistent model name"

Questions

1. Whats our model download validation sequence?
2. Is this a race condition or just bad sequencing?

This is a problem with verification of an url. I will work on this.
