shared/ is extracted to gitea.hostxtra.co.uk/vantage/vantage-shared and
pinned at v0.1.0 by server, agent, admin, sitesvc and vantagectl. The
replace directives and the ./shared entry in go.work are gone.
Every Go build now needs a credential for the private module: CI writes a
netrc per job from REGISTRY_USER + RELEASE_TOKEN and sets GOPRIVATE, and
the four Go Dockerfiles take it as a BuildKit secret rather than a build
arg, which would survive in the builder layer's history. RELEASE_TOKEN
needs read access to the vantage org.
admin, sitesvc and vantagectl now build from their own directory; only
server still needs the repository root, for default_steps/. The rebuild
triggers in server-deploy.yml lose their shared/ patterns, since a
service now moves when its own go.mod pin does.
The runtime stage is FROM scratch, which has no /tmp, so vulnsched died at
startup with "temp dir: stat /tmp: no such file or directory" and no scan
ever ran. Nothing in the server wrote to a temporary directory before the
trivy-db puller, which is why this only appeared now.
scratch cannot mkdir its own, so the directory is staged in the builder at
1777 and copied in. Also corrects CLAUDE.md, which described this image as
Alpine; the time/tzdata import it justifies is if anything more load-bearing
on scratch.
Also pins the explicit shared require in both go.mod files. `go mod tidy`
in workspace mode drops it, which breaks the Docker build where no
workspace exists.
