⚡ Bolt: Optimize ProgressPanel rendering #52
Conversation
Extracted `DownloadItem` component and wrapped it in `React.memo` to prevent unnecessary re-renders of the entire list during frequent WebSocket progress updates. Moved formatting helpers to `frontend/src/utils/formatters.ts`.

💡 What: Extracted
DownloadIteminto a memoized component and moved formatting logic to a utility file.🎯 Why: The
ProgressPanelwas re-rendering the entire list of downloads for every single progress update (which happens frequently via WebSocket), causing unnecessary DOM diffing and potential UI lag with many active downloads.📊 Impact: Reduces re-renders to only the specific item being updated.
🔬 Measurement: Verified via build and inspection of component structure. Functional behavior remains identical.
