- Insert 4/8 now inserts above the right-clicked node and shifts siblings
down instead of appending at end. Insert key shortcut (Shift+Ins = 4,
Ins = 8). Falls back to append when clicking empty space.
- Clear Value History uses a 5-cycle cooldown counter so heat stays gone
for ~1s instead of returning on the next async refresh.
- Right-click Search defers showFindBar via QTimer::singleShot so focus
isn't stolen by the closing context menu.
