// NewPackage creates a new [Package] node from a set of [File] nodes. It resolves
// unresolved identifiers across files and updates each file's Unresolved list
// accordingly. If a non-nil importer and universe scope are provided, they are
// used to resolve identifiers not declared in any of the package files. Any
// remaining unresolved identifiers are reported as undeclared. If the files
// belong to different packages, one package name is selected and files with
// different package names are reported and then ignored.
// The result is a package node and a [scanner.ErrorList] if there were errors.
//
// Deprecated: use the type checker [go/types] instead; see [Object].
