bug: Fail to get list model information: Unable to create model.list file

[0xSage]

A bit of a regression because models.list is still in progress. I know this is WiP, but I wanted to create this issue anyway, so we remember to check it works later on.

Cortex version

v75

Describe the Bug

• use v75 to download models
• run models list

❯ ls
llama3.1                          llama3.1.yaml                     stable-code-instruct-3b-GGUF      stable-code-instruct-3b-GGUF.yaml

❯ cortex-nightly models list

Questions:

• when do we create the models.list file?
• dynamically? i.e. only when some commands are executed
• along with the cortex installation? i.e. comes with cortexcpp folder?
• many edge cases on this front depending on our choices.
