Refactor-Cache-Invalidation-Service

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. Cache invalidation is scattered across repositories, event handlers, and HTTP controllers. Refactor toward one invalidation service with explicit keys.
