On sneak's rulings in sneak/prompts#113 and
sneak/prompts#130. REPO_POLICIES.md and
script/test, script/lint, script/docker and script/cibuild are the
sneak/prompts copies at 0653579: the scripts pass a new CACHEBUST value
instead of --no-cache, and the lint and test builds write no image. In
each Dockerfile stage the system packages and the Go module download
come above ARG CACHEBUST; every step that lints, tests or compiles, and
the node stages' yarn install, comes after it. Go's build cache and
golangci-lint's are cache mounts, and both go test runs carry -count=1.
README.md and TODO.md say the same.
