Please consider adding pub and proof to assets along side other files

Thanks for the tool! I've been writing a tool to install binaries from github releases and part of that is doing checksum and signature verification. Beyond my use case, it would be nice to have the public key and proof as part of the release assets so they are along side the rest of the files, this way it's easier to find and leverage for verifying the proofs.

Thanks.
