fix· Models
A model Anthropic won't serve now says so, instead of blaming your key
When Anthropic answers that your account can't use the task's model, the task now stops with a message naming the model and asking you to pick another.
Anthropic answers a model your account can't use, such as one your organization has disabled, with a "not found" error. On the Claude Code engine we read that as a rejected credential and told you to re-add your API key, which wouldn't have helped. On oh-my-pi the task only said an internal error had occurred. Both now say which model was turned down and point you at your model settings. We don't switch models for you, and replying won't help until you pick one your account offers.
