Subject: [PATCH] Add a test for the per name destructured export split

Four destructured names on one export statement must each get their
own node, and the old combined pattern syntax label must not survive
anywhere in the output.

+"""#2604 Class 2: an exported object-destructure assignment must emit one node
+per exported name, not one combined node for the whole pattern.
+
+`export const { auth, handlers } = NextAuth(config)` is NextAuth v5's own
+documented boilerplate (next-intl's `createNavigation()` is the same shape).
+Before this fix it collapsed to a single node whose id joined every
+destructured name (`stem_auth_handlers`) and whose label was the literal
+pattern syntax (`"{ auth, handlers }"`). A single-name import elsewhere
+(`import { auth } from './auth'`) looks for a node named `auth` alone, which
+never existed, so the import edge -- and any call resolved through it --
+dangled.
