make fmt and make fmt-check now cover every Markdown file with prettier
(4-space tabs, proseWrap always), as template-app-go does: prettier is
pinned by package.json and yarn.lock and runs in a docker build on a
digest-pinned node image, never on the host. The check is forced to run
with --no-cache-filter, as script/lint is.
script/fmt-check is split into a Go half and a Markdown half because the
Dockerfile lint stage cannot run docker: that stage now runs the Go half
and script/cibuild runs the Markdown half after the build. *.md leaves
.dockerignore so documents reach the build context.
README.md, TESTING.md and TODO.md are reformatted by make fmt; apart from
the README Entrypoints entries, its make fmt line under Building and the
TODO entry, that diff is mechanical.
Model: opus-5-5
script/fmt-check now runs goimports in list mode and fails naming any
file it would change, and checks gofmt with -s, as script/fmt applies
it. Both scripts run goimports with `go run` at the commit that
script/bootstrap used to install, so a goimports on PATH is never used
and bootstrap no longer installs it. The pin is written in both
scripts; change them together. The first run on a machine, and every
Dockerfile lint stage run, downloads and builds goimports.
The Markdown half of the issue (prettier) is not done here: it needs
node in the lint image or a separate build, a decision for the owner.
