Subject: Rename classes to OpcUa* prefix, replace BobinkNode with
 OpcUaMonitoredNode boilerplate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rename BobinkAuth → OpcUaAuth, BobinkClient → OpcUaClient (C++ class
names only; QML module URI and singleton name stay as Bobink).
Remove BobinkNode (QQuickItem-based) and add OpcUaMonitoredNode
skeleton using QObject + QQmlParserStatus, following Qt convention
for non-visual QML types.

-/**
- * @file   BobinkNode.h
- * @brief  QML component representing a single OPC UA node.
- *
- * Inherits QQuickItem so that monitoring is automatically tied to
- * visibility: when the item (or any ancestor) becomes invisible
- * (e.g. StackView navigates away, Loader unloads), the monitored
- * item is removed from the subscription.  When visible again,
- * monitoring resumes.
