astro
patch

Fixes a case where Astro allowed to call an action without using Astro.callAction. This is now invalid, and Astro will show a proper error.

---
import { actions } from "astro:actions";

-const result = actions.getUser({ userId: 123 });
+const result = Astro.callAction(actions.getUser, { userId: 123 });
