recognition_model was declared twice (once for the existence check, once for the
recognizer), so the node raised ParameterAlreadyDeclared at start-up and never
published. Declare each parameter once, and add a test that constructs the node,
since nothing else exercised it.
Recognition then works live: with the owner enrolled, 29 of 31 detections over
14 s were named, at detector scores around 0.9.
