Implemented `React.memo` for `ChatScrollNav`, `DownloadSessionButton`, `ReadingMapDriversPanel`, and `ReadingSummaryCard` to prevent unnecessary re-renders. Also appended `displayName` to each to satisfy linting rules.

💡 What: Added
React.memo()wrappers to four Chat/List components:ChatScrollNav,DownloadSessionButton,ReadingMapDriversPanel, andReadingSummaryCard, while maintainingdisplayNameproperties.🎯 Why: These are relatively complex components that frequently live in active chat loops. Re-rendering them unnecessarily whenever parent state shifts impacts performance, specifically in long chat threads.
📊 Impact: Expected to noticeably reduce wasted React render cycles and improve UI snappiness during chat streaming or scrolling.
🔬 Measurement: Verify by checking React DevTools profiler to see that these components now bail out of rendering when their props remain unchanged. Tests continue to pass smoothly.
