check / check (push) Failing after 3s
Run lint and tests as Dockerfile phases built with --no-cache (closes #202)
script/check, cibuild, docker, lint, test, setup and install-precommit
are now the sneak/prompts main copies, unchanged: lint and test each
build their Dockerfile phase with --no-cache. The lint phase runs
golangci-lint from the image REPO_POLICIES.md names, with libvips-dev
from apt-get; the test phase runs the tests with a 90-second timeout;
the build stage depends on both. script/bootstrap installs the C
compiler and image libraries only with --cgo, which the test phase and
build stage pass, and refreshes the apt lists before its first apt
install. Dockerfile.lint and CHECK_EPOCH are gone, and make
docker-versioned and docker-test call the scripts. Without VERSION the
build stage still uses git describe, per issue 166.

# VERSION is declared here, not earlier: a new value reruns only the

# comes from script/bootstrap): the tag on a tagged commit, tag-N-gHASH
# after one, the short commit when no tag is reachable. A context that
# carries .git and still yields no version fails the build; one without
# .git, as from a source tarball, stamps an empty version. CGO stays
# enabled for govips; -trimpath keeps build paths out of the binary, and
# -s -w leave out the symbol table and debug information.
