script/fmt now runs go fmt and then prettier --write on every Markdown
file; script/fmt-check runs the gofmt check and then prettier --check.
prettier is pinned in package.json and yarn.lock and configured in
.prettierrc with four-space indents and prose wrapped at 80 columns,
all copied from the sneak/prompts templates. After Go and the Go
modules, script/bootstrap uses an installed node or else a pinned one
through a hash-verified nvm archive, then an installed yarn or else a
pinned one, then the yarn dependencies. README.md is reformatted by
make fmt, and its Entrypoints section says what fmt, fmt-check and
bootstrap now do.
