Model catalog errors now flag when a credential specifically can't read the served list
What
When Claude Code fetches the server-provided list of models and gets back an error response, it now parses the error body to check whether the problem is credential-related. If so, it appends '(this credential cannot read the served list)' to the logged message and returns this more specific error, instead of a generic HTTP-status error.
Why
This makes it clearer, from the error itself, when the model list failed to load because of a credential permissions problem specifically, rather than an unspecified server error.
