Remove go vet step from CI and GNUMakefile

Remove the redundant go vet invocation from both the GitHub Actions
workflow and the GNUmakefile. The CI workflow no longer runs
"go vet ./..." and the "vet" target and its invocation in the makefile
are deleted.

This simplifies the build steps and avoids running go vet twice or as a
separate target, keeping linting/formatting tasks consolidated (e.g.
golangci-lint).
