Task 1 of the MQTT/Sparkplug B driver plan: MqttMode, MqttPayloadFormat, MqttProtocolVersion enums + MqttDriverOptions (broker conn + mode + nullable Sparkplug/Plain sub-options) per design doc §5.1. Removes the Task 0 temporary MQTTnet PackageReference from .Contracts (transport-free; references only Core.Abstractions). MQTTnet stays pinned in Directory.Packages.props for the .Driver project (Task 3). Claude-Session: https://claude.ai/code/session_01GASWkNEi68FSCtvr6rLoEW
