A plain `docker build .` stamped `dev`: `.dockerignore` left out `.git` and the Dockerfile defaulted VERSION to `dev`. `.dockerignore` now sends `.git` without `.git/config`. Given no build arguments, the builder stamps `git describe --tags --always` and the commit and date from git, and fails if `.git` is present but yields no version. The empty CHECK_EPOCH refusal is gone so the plain build succeeds. `script/version` now prints `git describe --tags --always --dirty`, so make, the scripts and a plain build agree. `vaultik version` treats the short commit and tag-N-gHASH forms as development builds, so they keep the development-build notice.
