Release v2.9.1

• Issue reports now include the device's stored scene, snapshot and effect data, so device-specific problems are analysable directly from the export.
• Diagnostics now also captures outgoing LAN commands, raw cloud-events messages and live error/rate-limit state, so "the adapter went silent" reports are traceable end-to-end.
• Groups now have their own diagnostics export button just like regular devices, so group-specific fan-out problems can be reported the same way.
• Appliance and sensor values are now reflected in the runtime state shown in the export, not only in the state tree.
