Reconcile this repository toward the opinionated "golden state" for agentic local development — a per-repo dev CLI, a thin justfile surface, a generated port-offset env contract, a four-file engineer skill, thin CI, and a doctor invariant-enforcer. Run /setup-engineer whenever you want to set up, audit, or repair a repo's local-dev tooling: a fresh repo with nothing, a half-built repo with organic scripts that needs consolidating, or a finished repo you just want to verify still conforms.
