Refactor-Feature-Flag-Resolver

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 plan, refactor, tests. Feature flag resolution combines defaults, environment overrides, tenant overrides, and user targeting in nested conditionals. Refactor to make precedence explicit.
