fix(node): full re-export fallback for unresolvable member re-exports (#34689)
Importing a named export from graphql-tag still failed with "does not
provide an export named 'gql'", even though #34363 added handling for
the `module.exports = require("X").MEMBER` entry shape that graphql-tag@2
uses. That fix narrows the wrapper's named exports to the names
statically attached to MEMBER inside X, which works when the attachments
are top-level but not for graphql-tag's actual inner file: a UMD bundle
that performs its `exports.gql = ...` and `gql.* = ...` assignments
inside the factory IIFE and builds the value through a namespace alias. Static
narrowing finds nothing there, so the wrapper advertised no names at
all.
When the member's attached names cannot be determined statically, fall
back to re-exporting the inner module wholesale rather than advertising
nothing. This matches Node, which over-approximates `require(X).Y` to
the inner module's full set of named exports. The narrow path is unchanged
for the cases where the attachments are statically known, so unrelated
names still do not leak through there.
