Refactored `KonvaCanvas.tsx` to significantly reduce unnecessary re-renders of `KnowledgeNode` components. - Wrapped `KnowledgeNode` in `React.memo` to prevent re-renders when props haven't changed. - Refactored event handlers in `KonvaCanvas` (drag, click, hover, context menu) to be stable functions using `useCallback`, avoiding the creation of new function references on every render. - Updated `KnowledgeNode` to accept these generic handlers and pass its own `node.id` when invoking them. - Combined drag move/end logic into stable handlers to avoid inline wrapper functions. This optimization ensures that operations like panning (which updates viewport state) do not trigger re-renders for all nodes on the canvas, improving frame rates during interaction.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

💡 What: Optimized
KonvaCanvasrendering by memoizingKnowledgeNodeand stabilizing event handlers.🎯 Why: Inline arrow functions in the render loop were causing all
KnowledgeNodecomponents to re-render on every state change (e.g., panning, selection), creating a performance bottleneck with many nodes.📊 Impact: Eliminates O(N) re-renders during viewport updates (panning/zooming) and unrelated state changes.
🔬 Measurement: Verified via code review that
KnowledgeNodeis memoized and all props passed to it are stable references. Linting passed.PR created automatically by Jules for task 3484183827827574747 started by @guangtouwangba
