feat(verify): enhanced Marionette verification with bidirectional communication

Browse Source 
Implemented undeniable proof that extension is actively executing:
- Added content script that communicates with background script
- Background script performs verifiable computation (value*2)+3
- Marionette test dispatches event, verifies round-trip communication
- Results stored in DOM attributes (no console.log dependency)
- Mathematical proof ensures extension code is actually running

Test verifies:
1. Content script injection and event listening
2. Message passing from content to background script
3. Background script computation and response
4. Full bidirectional communication chain
