* fix: handle PointId remapping when joining paths from different layers
When using Ctrl+J to join two points from different layers, the operation
failed because PointIds change during merge due to collision resolution.
The fix uses index-based point tracking instead of PointIds:
1. Before merge: Record the index of each selected point in its layer
2. Calculate post-merge indices using the point offset from layer1
3. After merge: Retrieve the actual PointIds at those indices
4. Create the connecting segment using the resolved PointIds
This works because Vector::concat() preserves point ordering during merge,
so we can use exact index arithmetic to find points after remapping.
