/// Create an evaluator in the authenticated project.  Use evaluators to define **how** Langfuse should score data: the prompt, the expected structured output, and the optional model configuration.  Naming behavior: - If this is a new evaluator name in your project, Langfuse creates version `1`. - If the name already exists in your project, Langfuse creates the next version and returns it. - When a new project version is created, existing evaluation rules in that project automatically move to the newest version for that evaluator name.  Recommended workflow: 1. Create the evaluator. 2. Read the returned `variables` array. 3. Read the returned `outputDefinition.dataType` so the client knows whether future scores will be numeric, boolean, or categorical. 4. Create one or more evaluation rules that reference the returned evaluator family using `name` and `scope`.  Recovery guidance: - `422` with `code=evaluator_preflight_failed`: the evaluator cannot run with the resolved model configuration. Add a valid explicit `modelConfig`, or configure the project's default evaluation model, then retry the same request. - `400` with `code=invalid_body`: the request shape is malformed. Use the structured `details.issues` array to fix the specific fields and retry. - `400` with `code=invalid_body` on `outputDefinition`: send `dataType`, `reasoning.description`, and `score.description`. Do not send `version`; it is not part of the public request shape.  Unstable API note: - This surface may evolve while the underlying evaluation data model is being redesigned.
