Pull Request Overview
This PR implements the unicorn/prefer-response-static-json rule, which enforces the use of Response.json() over new Response(JSON.stringify()) for creating JSON responses in web APIs.
- Adds detection logic for
new Response(JSON.stringify(data))patterns - Provides clear diagnostic messages suggesting the preferred
Response.json()alternative - Includes comprehensive test coverage with both passing and failing cases
