Optimize Component Rendering with Memoization

Problem:
Several components re-render unnecessarily, especially in the chat interface.

Recommendation:
Apply memo, useCallback, and useMemo more consistently across components.

// Example optimization for app/components/chat-input/suggestions.tsx
const MemoizedSuggestion = memo(function Suggestion({ suggestion, onClick }) {
  return (
    <PromptSuggestion onClick={() => onClick(suggestion)}>
      {suggestion}
    </PromptSuggestion>
  );
});

// Update parent component
export const Suggestions = memo(function Suggestions({
  onValueChange,
  onSuggestion,
  value,
}: SuggestionsProps) {
  // Existing code...
  
  const handleSuggestionClick = useCallback(
    (suggestion: string) => {
      setActiveCategory(null);
      onSuggestion(suggestion);
      onValueChange("");
    },
    [onSuggestion, onValueChange]
  );
  
  // Updated return with memoized child components
  return (
    <AnimatePresence mode="popLayout">
      {showCategorySuggestions ? (
        <motion.div>
          {activeCategoryData?.items.map((suggestion: string, index: number) => (
            <MemoizedSuggestion 
              key={`${suggestion}-${index}`}
              suggestion={suggestion}
              onClick={handleSuggestionClick}
            />
          ))}
        </motion.div>
      ) : (
        // Rest of the component...
      )}
    </AnimatePresence>
  );
});

Impact: Medium/Low - Reduces unnecessary re-renders
