Dayuan Jiang 443a937370 fix: prevent duplicate diagram history entries on message send (#48) ...

When sending a message, the history was being added twice because:
1. handleExport() triggers exportDiagram() which adds to history
2. AI responds and loadDiagram() is called, which internally triggers
   another export event in DrawIO, adding a duplicate entry

Added expectHistoryExportRef flag to track user-initiated exports and
only add to history when the export was explicitly requested.
