Visit a STopLevelVariableDeclaration.

Implementation

@override
void visitTopLevelVariableDeclaration(STopLevelVariableDeclaration node) {
  // Does nothing for global variables in this pass (handled by InterpreterVisitor)
  for (final variable in node.variables?.variables ?? []) {
    final varName = variable.name?.name ?? '';
    if (varName == '_') {
      // Ignore wildcard variables
      continue;
    }
    // For now, just define the variable name with null.
    // The actual initialization will happen in InterpreterVisitor.
    if (!environment.isDefinedLocally(varName)) {
      environment.define(varName, null);
      Logger.debug(
          "[DeclarationVisitor] Defined top-level variable placeholder '$varName' in env: ${environment.hashCode}");
