- Selected edge shows interactive dots at both endpoints; drag onto any
handle (different snap point or different node) to reconnect. Edge
follows the cursor live during drag; drop on empty space leaves edge
unchanged.
- Endpoint dots render in EdgeLabelRenderer above the node layer and walk
the elementsFromPoint stack so the underlying handle wins over the
dragged dot itself.
- ProxmoxGroupNode in container mode now renders bottom_handles snap
points (was always single 'bottom' handle), matching BaseNode.
- New canvasStore.reconnectEdge action: swaps source/target/handles via
normalizeHandle, snapshots history, marks dirty.
