check / check (push) Waiting to run
Let a plain docker build pass and stamp the git version (closes #57)
The size tests skip a case whose secret needs more locked memory than
the process can lock, found by locking a buffer of that size: memguard
panics otherwise, and a plain `docker build .` runs under an 8 MiB
RLIMIT_MEMLOCK. script/cibuild, or any process allowed to lock past the
limit, runs every case.

The build stage stamps the VERSION build argument, else
`git describe --tags --always`, and fails when .git is present but
yields no version. `make build` stamps `git describe` too instead of
the fixed 0.1.0. .dockerignore keeps .git/config out; script/docker is
now the canonical copy.
