"""Show a concise local node summary over serial.
Purpose: read local node identity and metadata in one place.
Transport scope: Serial only.
Behavior: reads node database, prints local node ID/name/hardware model.
Expected output: 1-3 summary lines describing the local node.
Cleanup/error handling: closes interface on exit and prints clear errors on failure.
