Cost-Generation-Snake-To-Camel

The model receives the prompt (and optional system message). The run uses scorer rubric_json_metrics with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Return JSON only with keys benchmark, title, code, done. Set benchmark to "cost", title to "Convert snake_case to camelCase", and done to true. Implement snakeToCamel(value) for lowercase snake_case strings.
