Walk me through the "scaffold a Service Contract" recipe.

Goal: turn a Resource Model into a Magento-style service contract. Prompt: "Generate Api/<Entity>RepositoryInterface.php, Api/Data/<Entity>Interface.php, Api/Data/<Entity>SearchResultsInterface.php, plus the Model/<Entity>Repository.php implementation, all wired in etc/di.xml with preference for the interface. Use the existing ResourceModel/<Entity> and ResourceModel/<Entity>/Collection, do not change them." Files: 5. Verify: bin/magento setup:di:compile + vendor/bin/phpstan analyse Api Model + a quick REST GET /V1/<entity>/{id} call after adding a webapi.xml route. Time: 10 minutes start to first green test.
