Subject: [PATCH] Make Vue nodes read-only when in panning mode (#5574)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

Integrated Vue node components with canvas panning mode to prevent UI
interference during navigation.

## Changes

- **What**: Added
[canCapturePointerEvents](https://docs.comfy.org/guide/vue-nodes)
computed property to `useCanvasInteractions` composable that checks
canvas read-only state
- **What**: Modified Vue node components (LGraphNode, NodeWidgets) to
conditionally handle pointer events based on canvas navigation mode
- **What**: Updated node event handlers to respect panning mode and
forward events to canvas when appropriate

## Review Focus

Event forwarding logic in panning mode and pointer event capture state
management across Vue node hierarchy.
