cibuild: the org model, which runs every check uncached (closes #37)

script/cibuild was a plain docker build ., so on a tree Docker had
seen before every check step came from the build cache and the build
still passed. It is now the org model from sneak/prompts, byte for
byte: it runs script/bootstrap and script/check, then builds the image
with --no-cache and the git describe version as the VERSION build
argument, which the Dockerfile's builder stage already declares.
README.md's entry for the script says what it now does.
