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

A plain `docker build .` now stamps the version from git rather than `dev`/`0.0.0`. After `tsc`, `script/build` writes into `dist/package.json` the version `script/version` decides: `VERSION` when given, otherwise `git describe --tags --always` (the tag; or tag, commits since and short commit; or the short commit), otherwise `package.json`'s. A checkout with `.git` that yields an empty, `dev` or `unknown` version fails the build. `.dockerignore` sends `.git` but not `.git/config`, so no remote URL or credential reaches the image. `ARG VERSION` has no default, and the host scripts' version still wins. Not changed: `REPO_POLICIES.md` still says `ARG VERSION=dev` until the shared policy changes. Model: opus-5-5 Co-authored-by: clawbot <sneak+clawbot@sneak.cloud>

+# script/version: print the version script/build stamps into the built
+# package. Our own extension to scripts-to-rule-them-all.
+#
+# Order of precedence:
+#
+#   1. $VERSION, if set and not empty: an explicit value, such as the
+#      Dockerfile's VERSION build arg.
+#   2. If this checkout has .git, `git describe --tags --always`: the tag
+#      on a tagged commit; the tag, the commits since it and the short
+#      commit on a later commit (v1.2.3-4-gabc1234); the short commit when
+#      no tag is reachable.
+#   3. Otherwise, as in a source tarball, the version package.json declares.
+#
+# A checkout with .git whose version still comes out empty, dev or unknown
+# fails: git is missing or could not read the checkout, and the build could
+# not be traced back to its commit.
