Added Service Worker unregistration and IndexedDB clearing support.

• Added: Service Workers now unregister per-site (active tab only)
• Added: IndexedDB clearing for Firefox ≥103
• Fixed: Popup now shows actual parent domain (e.g., aliexpress.com)
• Fixed: Service Worker unregistration only targets active registrations

What’s new in v1.2.0:

🌐 Domain-chain clearing
• Now clears cookies/cache for both the current domain and its parent domain (e.g., clearing www.google.com also clears google.com)
• Ensures full logout on services like Gmail, Amazon, and Facebook

🎨 Clearer user experience
• Popup now explains why this resets login state ("…including parent domains to log you out")
• Options page clarifies LocalStorage is cleared only for the current tab (not all tabs)

♿ Accessibility & inclusivity
• Full keyboard navigation support with visible focus rings
• Screen-reader-friendly labels and ARIA roles in dialogs

⚡ Reliability
• Fallback to full cache/cookie clear if domain-based removal fails (e.g., on localhost or unusual domains)
• History search narrowed to last 30 days for faster, safer deletion

🔒 Privacy-first
No data leaves your browser. Everything runs locally — even the domain chain logic.

🔍 Why this matters:
Modern sites store auth cookies on root domains (e.g., .google.com), not just subdomains. This update ensures true reset — no more staying logged in after clearing!

⚠ Note: LocalStorage/sessionStorage are cleared only in the active tab (a Firefox security limitation). Use "Clear data" in DevTools for full-site reset.

The popup is now displayed in the center of the screen.
