ci: scanner workflows clone needed sibling repos

The Tier 1 CodeQL + govulncheck workflows failed on PR #5 because
cli uses replace directives for sibling repos that weren't cloned.

Fix: each workflow now checks out cli into ./cli, plus clones the
public sibling repos cli actually depends on (per its go.mod).
