fix: navigator.languages should include base language per spec

Browse Source 
Per the HTML spec, navigator.languages should return the user's
preferred languages. Most browsers return at least ["en-US", "en"]
to include the base language tag alongside the regional variant.

This matches Chrome, Firefox, and Safari behavior and improves
compatibility with sites that check for language negotiation.
