Subject: [PATCH] gui: emit dataChanged on block close for segment updates

When a complete block arrives in a single streaming chunk, the QML
Repeater may not pick up intermediate segment updates because the
event loop hasn't run. Emit an explicit dataChanged with SegmentsRole
when [[[end]]] closes a block, ensuring the delegate shows the final
rendered content.
