// unifi's tools — its own code (novox/hq ADR 0039), importing unifi's own client. They return
// structured data; the mesh serves them through the sdk's tool harness. unifi is tools-only (no
// events entrypoint): the controller does not push lifecycle events the mesh consumes, so this
// module reads its resources — port forwards, devices, clients — and exposes them, and stops there.
