Proposal for auth in frames v2

https://github.com/farcasterxyz/protocol/discussions/211

very bad feeling around using siwf in the current form

can we ship Farcaster Connect first or at least around the same time?

I think the flow works a lot better in the frame context since it can be controlled by the Farcaster client serving as a host rather than a standalone library

this means you can immediately sign Super custodying users and direct others through another flow — my guess for the other flow is that an approach similar to AuthKit will work in this context for now

happy to chat more online about our thinking, we are open to feedback
