Eliminated the custom site history dropdown UI and its related event handlers from script.js. Updated Electron to version 37.2.4 in package.json and package-lock.json. Cleared entries from search-history.json and site-history.json.
Site history is now managed in localStorage for faster access and better cross-tab experience, with file sync for persistence. Added a dropdown for quick site history access in the address bar, updated settings page to display and manage site history from localStorage, and improved history recording logic in both main and renderer processes. Also added debug info and test data utilities for development.
