The binaries job built with GOPRIVATE='' so go verified the first-party
luxfi/* modules against the public sumdb — force-moved upstream tags never
match, so every release failed with 'checksum mismatch / SECURITY ERROR'
(luxfi/vm@v1.3.1). Set GOPRIVATE + GONOSUMDB for luxfi/* + hanzoai/* and add a
git-config token (GH_PAT, GITHUB_TOKEN fallback) so the modules resolve directly
via git and skip the sumdb. Dockerfile: GONOSUMCHECK (removed by Go) -> GONOSUMDB,
guard the token, x-access-token form; docker job passes GH_PAT so it can read
luxfi.
