🔧 How It Works

1. Content Script scans every page you vist for:
   • Login forms (<input type="password">)
   • Privacy-related links (e.g., /privacy, /terms)
2. Background Service Worker:
   • It queues and throttles the data from pages you visit
   • Sends it to the Go backend (/monitor)
   • Maintains extension state (active/paused)
3. Go Backend (Gin + Colly):
   • removes duplicates entries using policy link hashes
   • Scrapes the text from linked policy pages encountered
   • Maintains a stack of the sites you’ve visited and scanned
4. Popup UI:
   • Shows you how many login forms and policy links were found
   • Lets you toggle monitoring on or off
   • Displays the last URL you scanned for quick reference
