Moves out youtube from packages/ui to the main source
Moves and cleans up the iframe feature
The notification flows go through the background process and single content script (avoids duplication of the mounting mechanism in Youtube content script)
Adds pages/notifications to group all notifications in one path
Cleans up the opera-serp util
Adds debugMode for easier testing and stagingMode for allowing engines to update from staging CDN
I tested the Youtube Wall notification (Chrome, Firefox, Safari) and Opera Serp (Opera).
