Subject: [PATCH] Migrate to Chrome Manifest V3

- Update manifest.json to use Manifest V3 format with service_worker
- Replace chrome.browserAction API with chrome.action API
- Fix XMLHttpRequest error in Service Worker by using native fetch
- Update @types/chrome to v0.1.4 for proper Manifest V3 types
