Use `CreateAsyncScope` in Async Methods
`CreateScope()` used in async flows where async disposal is needed, including async methods, lambdas, local functions, anonymous methods, and top-level programs that use `await`. Detection covers regular member access (`_scopeFactory.CreateScope()`) and conditional-access receivers (`_scopeFactory?.CreateScope()`, `_provider?.CreateScope()`) alike.
