Stamp the git tag or short commit into the binary (closes #4)

A plain `docker build .` now stamps the version into bsdaily: the VERSION build argument when one is given, otherwise `git describe --tags --always` of the .git in the build context. The build fails if the context carries .git and no version comes out. A host `make` build stamps the same `git describe` value. bsdaily prints it with --version. The new .dockerignore is the canonical copy, which keeps .git/config out of the build context. script/docker is replaced with the canonical copy, which passes the version it derives on the host.

 # Completed Steps

+- 2026-10-02: A plain `docker build .` and a host `make` build stamp the git tag
+  or short commit into the binary, which `bsdaily --version` prints; added the
+  canonical `.dockerignore`, which keeps `.git/config` out of the build context.
