feat: heyanoun message channel for all noun holders

[lsankar4033]

updating merkle root for all nouners, prompt on main site

known tasks:

• backend storage/updating of group on every erc721 xfer
• new frontend prompt + middleware to support new group

[lsankar4033]

could have a separate tab for this

[lsankar4033]

might be valuable to have an endpiont where the root is shown at any point in time (as long as the list of addresses included)
