wapm-cli "scan" CI that scans the registry for broken packages

[fschutt]

Maybe this is more something for the backend, but it happens a lot that the registry contains broken packages (because wapm-cli evolves a lot). We could make a "scan" command, that regularly scans the registry and returns a list of packages that cannot be run, similar to a "fuzzer", then warns the user of the failing package.

{
  search(kind:PACKAGE, query:"", first: 1000) {
    edges {
      node {
        ...on PackageVersion {
          package {
            name
          }
        }
      }
    }
  }
}
