build: add Docker image CI smoke test #16

Fixes #3

Add a community Dockerfile for tack and cover it in Buildkite so it does not drift unnoticed. The Docker build uses the Go version pinned by go.mod, installs CA certificates in a slim Debian runtime image, and keeps common local artifacts out of the Docker build context.

The new Buildkite step builds the image and runs tack -h, matching the existing Nix package smoke test without requiring runtime configuration, credentials, or external services.
