Replace the repo-owned release workflow with the shared go-release workflow.
It must run tests, calculate the version, and call goreleaser with ghcr.io Docker builds.
The release now triggers only on Go, module, Dockerfile, or goreleaser changes.
Add the shared go-pr workflow for pull request checks.
Add the shared go-autoupdate workflow to refresh go.mod and go.sum daily.
The workflow calculates the version with semver-generator, tags the
commit when the version is new, and runs goreleaser. goreleaser ships
two distribution paths: tar.gz binaries for darwin and linux on amd64
and arm64, and a multi-arch ghcr.io container that carries the go,
python3, and C toolchains so the exec evaluators run in-container.
The new llmtest version subcommand reports the stamped build version.
