script/docker and script/cibuild are again byte-identical to the shared model
scripts. Both compute the version on the host with git describe, pass it as the
VERSION build arg and build with --no-cache; script/cibuild runs
script/bootstrap and script/check first. The CI build now stamps a real version
instead of unknown.
make build compiles with -trimpath and -s -w, as the model Dockerfile does.
script/version stays: the Makefile and the Dockerfile still use it.
The README describes both scripts as they now are.
Model: opus-5-5
`make fmt` formatted only Go, so the org's Markdown settings were unenforced and Markdown was wrapped by hand. prettier, pinned in `package.json` and `yarn.lock` beside ESLint, now formats the Markdown with `.prettierrc` (4-space tabs, `proseWrap: always`). It runs only in Docker: `make fmt` writes the formatted files back without a bind mount, and `make fmt-check`, `make check` and the image build fail on unformatted Markdown. The image build's lint stage now runs the Go format check directly and no longer installs `make`. `README.md` and `TODO.md` are reformatted with no word changed: the README reflows from 72 to 80 columns.
