Enhanced several diagnostic messages in the linter by adding helpful suggestions. This includes guidance for:

  • No named exports found in a module
  • Multiple exports of the same name
  • Missing exports in imported namespaces
  • Computed references to namespaces
  • Assignment to members of namespaces
  • Anonymous default exports

These improvements aim to provide clearer instructions for resolving common issues encountered during linting, enhancing the overall developer experience.
