Pull Request Overview

This PR prevents the transformer from converting declare global into declare namespace global and updates the expected baselines accordingly.

• Adjusted the module-declaration transformer to preserve the global keyword.
• Updated all relevant test baselines to use declare global.
• Removed redundant export {} lines in the baselines where appropriate.

I think this is probably fine, but does require a merge from main and baseline update.
