Keep modules, lint cache and system packages in check builds (closes #130)

On sneak's ruling in #130, check
builds may keep three more things besides Go's build cache. In each stage
of the canonical Go Dockerfile, the system-package install and the module
download now come before ARG CACHEBUST, so Docker keeps those layers until
the base image, the install line, go.mod or go.sum changes. The modules
are kept as a layer, not a cache mount, because Go does not check a cache
mount's files again. golangci-lint run also mounts golangci-lint's cache.
Every step that lints, tests or compiles still comes after ARG CACHEBUST
and reruns on every check build, and both go test runs keep -count=1. The
policy, both checklists, the Go style guide, the README and the script
comments state the rule the same way.

# Completed Steps
- 2026-10-18: Check builds may now also keep Go's downloaded modules,
golangci-lint's cache and the layers that install system packages (issue 130),
on sneak's ruling there. In each stage of the canonical Go `Dockerfile`, the
system-package install and the module download (`COPY go.mod go.sum ./`,
`RUN go mod download`) come before `ARG CACHEBUST`, so Docker keeps them until
the base image, the install line, `go.mod` or `go.sum` changes. The modules
are kept as a layer, not a cache mount, because Go does not check the files in
a cache mount again. `golangci-lint run` also mounts golangci-lint's cache,
`/root/.cache/golangci-lint`. Every step that lints, tests or compiles still
comes after `ARG CACHEBUST` and runs on every check build, and both `go test`
runs keep `-count=1`. `REPO_POLICIES.md`, both checklists, the Go style guide,
the README and the script comments state the rule the same way. This repo's
own `Dockerfile` is unchanged: its `script/bootstrap` step also installs node
packages, which the ruling does not cover. Repositories pick this up on their
next re-vendor.
- 2026-10-15: Check builds now keep Go's build cache between runs (issue 113),
on sneak's ruling there that Go's compile cache may survive. `script/lint`,
`script/test`, `script/cibuild` and `script/docker` pass a new `CACHEBUST`
