Bug fixes

Fixed page refresh causing "Access to the file was denied" error — the extension now uses hash-based routing so refreshing always loads correctly
Fixed Live Watching not updating in real time — the service worker now persists watched origins to session storage so they survive when the SW goes idle
Selected tab (Cookies, localStorage, sessionStorage) is now preserved on page refresh
Improvements

Adding an origin without https:// now auto-prefixes it and lets you correct the protocol before confirming
Theme changes (dark/light) now animate with a smooth transition
Removed the Simple/Advanced toggle — all columns are always visible
Settings page now has a close button
Cleaned up Settings — removed unused "Default search mode" option
