function anthropic.internal._reject(detail: string) -> ai.errors.InvalidRequest

(internal) Every LOCAL, pre-send rejection in the Anthropic client throws ONE error identity: ai.errors.InvalidRequest with a null status code — the class the Responses, Google, Images and Bedrock clients already use.

It matters that this is an ai.errors.Failure and not baml.errors.InvalidArgument: ai.errors.normalize flattens a non-Failure into an untyped baml.errors.UnknownError, and ai.Fallback only advances to the next member on a TYPED failure. A missing key in one member of a fallback chain has to fall through, not abort the chain.
