Fixed issue where bars would snap back to original position on drag release.
Problem:
- On mouseup/touchend, we cleared draggedPercentage immediately
- Conversions hadn't updated yet (async state updates)
- Bar switched from draggedPercentage to old item.percentage
- Bar visually "snapped back" to original position
Solution: Delay clearing drag state until conversions update
- On drag end: only clear draggingUnit, keep draggedPercentage
- Added useEffect that watches conversions + draggingUnit
- When !draggingUnit && draggedPercentage !== null → drag just ended
- This means conversions have updated, safe to clear visual state
- Now clears draggedPercentage and baseConversionsRef
Flow:
1. User releases mouse/touch
2. handleMouseUp/handleTouchEnd: calls onValueChange(..., false)
3. Sets draggingUnit = null (stops active drag)
4. Keeps draggedPercentage (maintains visual position)
5. MainConverter updates inputValue and selectedUnit
6. Conversions recalculate
7. useEffect detects: !draggingUnit && draggedPercentage
8. Clears draggedPercentage → bar smoothly transitions to calculated position
Result: Bar stays at dragged position and smoothly settles to final value!
