Re-vendors REPO_POLICIES.md, script/cibuild, script/docker, script/lint and script/test from sneak/prompts next at 0653579, on sneak's ruling in sneak/prompts#130. In the lint, test and builder stages of the Dockerfile, the module download, and in builder the apk install, move above ARG CACHEBUST, so Docker keeps those layers until the base image, the install line, go.mod or go.sum changes. golangci-lint run also mounts golangci-lint's cache. Every step that lints, tests or compiles still comes after ARG CACHEBUST, and go test keeps -count=1 and -race. README and TODO.md say the same. Model: opus-5-5
