Wrapped the StarRating functional component in React.memo to prevent unnecessary re-renders. This optimization is targeted at its usage within list components like BookRow, where parent state changes would previously cause every StarRating instance to re-render, even if its props were unchanged. This improves UI performance by reducing the number of wasted render cycles.
…7328919 ⚡ Bolt: Memoize StarRating component to prevent re-renders
💡 What: Refactored `CircularProgressBar` to a functional component and memoized expensive geometric calculations using the `useMemo` hook. 🎯 Why: The component was recalculating `center`, `radius`, and `circumference` on every animation frame (up to 60 times per second), causing unnecessary CPU work. 📊 Impact: Reduces rendering overhead by ensuring geometric calculations only run when the `size` or `strokeWidth` props change, not on every frame. This leads to smoother animations and lower CPU usage. 🔬 Measurement: This can be verified by observing smoother performance on pages with many progress bars or by using the React DevTools profiler to confirm the component's render logic is not re-run on every animation frame.

This submission optimizes the
CircularProgressBarcomponent by refactoring it to a functional component and using theuseMemohook to cache expensive geometric calculations. This prevents redundant computations on every animation frame, reducing CPU overhead and leading to smoother animations, especially on pages with multiple progress bars. The change also modernizes the codebase by converting a class-based component to use modern React hooks.PR created automatically by Jules for task 2356606131163095690 started by @Smensink
