docker build . stamps the git tag or short commit, not dev (closes #154)

script/build writes the version script/version prints into
dist/package.json, which quak --version reports: the VERSION environment
variable or build arg when one is given, otherwise git describe --tags
--always, otherwise package.json's version. A checkout with .git whose
version comes out empty, dev or unknown fails the build.

.dockerignore no longer leaves out .git, and ARG VERSION has no default,
so a plain docker build . of a clone stamps its commit. script/docker and
script/cibuild still pass the host's version. make build-bin bundles the
built dist/, so the single binary reports the same version.

places, and reads `.gitignore` as its default ignore file — which is why
`.dockerignore` keeps `.gitignore` in the build context.
### Version
`quak --version` reports the `version` of `dist/package.json`, which
`script/build` writes after compiling; the repo's own `package.json` keeps
`0.0.0`, and that is what the tests, which run from source, report.
`script/version` decides what is written:
- the `VERSION` environment variable, or the `Dockerfile`'s `VERSION` build arg
(`--build-arg VERSION=...`), when one is given and not empty;
- otherwise, in a checkout with `.git`, `git describe --tags --always`: the tag
on a tagged commit, otherwise the short commit;
- otherwise, as in a source tarball, the version `package.json` declares.
The build fails if the checkout has `.git` and the version still comes out
empty, `dev` or `unknown`: such a build could not be traced back to its commit.
`.dockerignore` therefore does not leave out `.git`, so any `docker build .` of
a clone stamps the commit it was built from; a shallow clone of one branch has
no tags and stamps the short commit. `script/docker` (and so `make docker`) and
`script/cibuild` pass the version they resolve on the host, with `--dirty`, as
the build arg, which takes precedence. The image's
`org.opencontainers.image.version` label carries that build arg only, so a build
given none leaves it empty. `make build-bin` bundles the built `dist/`, so the
single binary reports the stamped version too.

# Completed Steps
- 2026-10-02: `docker build .` stamps the commit's tag or short commit, not
`dev` (issue 154). `script/build` writes the version `script/version` prints
into `dist/package.json`: the `VERSION` environment variable or build arg when
one is given, otherwise `git describe --tags --always`, otherwise the version
`package.json` declares. `.dockerignore` sends `.git`, and a checkout with
`.git` whose version comes out empty, `dev` or `unknown` fails the build.
`make build-bin` bundles the built `dist/`, so the single binary reports the
same version.
