Nova AI v2.6.7 — Fixed Scroll-to-Bottom During Streaming

Fixed: Scrolling to Bottom While AI is Streaming

The previous fix only half-worked. The real bug was:

• isNearBottom() used findLastCompletelyVisibleItemPosition()
• During streaming, the message is growing — it is never "completely visible"
• So the check always returned false, auto-scroll stopped, and you got pushed up

Fix: Now uses findLastVisibleItemPosition() and the userScrolledAway flag is the only gate. If you haven't scrolled away, you stay pinned to the bottom.
