Pull Request Overview

This refactoring removes the dependency on AstNodes::get_node for the check_unresolved_exports function by restructuring how unresolved exports are checked. The change moves from traversing unresolved references to directly iterating over AST nodes.

• Removes the root() method from UnresolvedReferencesStack
• Moves check_unresolved_exports from checker/mod.rs to javascript.rs
• Changes the implementation to traverse program statements directly instead of using unresolved references and node lookup
