⚡ Bolt: Memoize QueueEntry components - #1273
Conversation
💡 What: Added `React.memo()` to `QueueEntry`, `_QueueEntry`, `TodoQueueEntry`, and `NonTodoQueueEntry` components in `client/src/QueueEntry.tsx`. 🎯 Why: These list item components were re-rendering unnecessarily when the parent list updated, leading to performance bottlenecks during scrolling in virtualized lists. 📊 Impact: Reduces re-renders by skipping reconciliation when props (`node_id`, `index`) haven't changed, making scrolling and rendering significantly faster. 🔬 Measurement: Verify with React DevTools Profiler that `QueueEntry` components don't re-render on unrelated state updates.

This commit adds four memoization boundaries but modifies only QueueEntry.tsx, leaving the behavior untested. Add a component regression test that verifies an unchanged item skips parent-driven renders while Redux updates such as status, text, and node removal still refresh the item; otherwise a future change could turn this optimization into stale queue UI without detection.
