Keep Go's build cache in check builds: re-vendor sneak/prompts e3f79c4 (closes #129)
The vendored files are copies from sneak/prompts e3f79c4, with this
repository's own entries kept. The script/ builds pass a new CACHEBUST
value instead of --no-cache, which emptied Go's build cache mount, so
every make test compiled the standard library and every dependency with
-race. Every Dockerfile stage declares ARG CACHEBUST first, so every RUN
step still reruns on an unchanged tree. The steps that compile mount
Go's build cache, and both go test runs keep -count=1. The lint and test
builds write no image. script/bootstrap, script/fmt and script/fmt-check
are the canonical files plus this repository's Go steps.

# script/docker: build the Docker image tagged with the project name.
# Identical in all repos; the tag comes from script/projectname.
# A new CACHEBUST value reruns every RUN step, since a cached gate phase
# is a check that did not run; unlike --no-cache, it keeps Go's build cache.
# This relies on every stage of the Dockerfile declaring ARG CACHEBUST
# first; a stage without that line is served from cache on an unchanged
# tree, with no warning.
