fix: Removed unused V1.

[davinchia]

We do not use V1. Instead of duplicate, potential drift and confusion, let's remove V1 for now and re-introduce when we are ready to move to V1.

I'm more confused about the difference between "v0" and the root item, which are different files and not symlinks - what's up with that?

[davinchia]

Me too! I had to check with @gosusnp and @jdpgrailsdev to clarify:

• this is leftover from when we tried to go to V1. We ended up backing out because the work was too involved.
• in the original proposal, the root file was supposed to be a symlink to the protocol file in v0, so we only updated one place even after the back out.
• it looks like we lost that in the move to this repo. Looking at the platform repo, it looks like we use both packages, which means we need to update both files..
• I'm going to open a follow up conversation in our channel to clear some of this up. I think we should handle resolving this in a separate PR.
