[WIP] Add system for proxy passthrough functionality

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

add a system for the proxy that alows passthrough. go back to befor this new iframe system, and add a methood where the proxy records the origonal google url that loads in the html of cloudmoon, and opens that up in a seprate window, avoiding the proxy and alowing sign in, where the link should load around /html/body/div[1]/main/div[2]/div/div/div/button. also intersept this link and open it in a new window manualy to avoid proxying.
