Added

• Connectivity tests, unpublished: client.connectivity_tests starts and stops
  an on-demand reachability/authentication probe against a classic device or a
  network endpoint (start/stop, one name or a DeviceSet, dispatched to
  the endpoint variant by a fixed query on the same path), reads the result
  Forward already publishes for scheduled collection (SourceConnectivityResult),
  and reads the same result broken into its six phases -- connection,
  authentication, type discovery, setup, authorization, query -- each a
  discriminated union generated as a RootModel, so phase.root gets the
  concrete phase. Requested by the change-demo integration, which found the
  GUI's "Test connectivity" button backed by no SDK surface at all. Verified
  live: a device tested end to end through all six phases, an endpoint tested
  through the dispatched variant, both singly and in bulk; nothing is left
  behind since starting or stopping a test never touches a snapshot.
