Summary
This PR updates the CORSMiddleware documentation to explain how to configure it globally.
By wrapping the entire Starlette application with CORSMiddleware, all responses—including error responses generated by unhandled exceptions—will consistently include the proper CORS headers. This change reflects recent discussions (see discussion #2876) and clarifies the recommended usage pattern for ensuring global CORS enforcement.
