Exit codes when model call fails

[cboecking]

There are times when a model call fails. aichat should return a non-zero error code when this happens.

Here is an example where aichat works as expected. When the file is not present, aichat returns the error and an error code greater than zero. As a result, the starship prompt shows a red > prompt.

Here is an example where aichat experiences a model error when using claude. aichat return the error message; however, it return a 0 error code. As a result, the starship prompt shows a white > prompt.

In order for me to create well behaved scripts, I need aichat to return a non-zero error code in these circumstances.
