## Summary
- Dagger shells out to the `docker` binary to provision its BuildKit engine container
- Phase 3 removed `docker-ce-cli`, breaking all `dagger call` invocations in CI
- This restores `docker-ce-cli` (without buildx/skopeo — those aren't needed)
## Test plan
- [ ] Build locally, release as v3.0.2, update manifest, sync
- [ ] Trigger docs build workflow and verify Dagger engine starts
