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, or dev when it yields nothing. bsdaily logs the version on the first line of every run and prints it with --version. The new .dockerignore is the canonical copy, which keeps .git/config out of the build context, plus this repo's host-built artifacts. script/docker is replaced with the canonical copy, which passes the version it derives on the host.
