⚡ Bolt: wrap TribePostListItem in React.memo()

[google-labs-jules]

💡 What: The optimization implemented
Wrapped the TribePostListItem functional component in React.memo() and added explanatory comments.

🎯 Why: The performance problem it solves
The Tribe component renders a long list of TribePostListItem components. Whenever the parent Tribe component re-renders (e.g., due to scroll updates, fetching new data, state changes), all list items would unnecessarily re-render even if their individual props hadn't changed. These items are complex and contain heavy components (like Markdown, Img, interactions), making re-renders extremely expensive.

📊 Impact: Expected performance improvement
Reduces unnecessary re-renders of list items in Tribe.tsx when the parent state updates but individual post data remains stable. This results in faster scrolling, reduced main-thread blocking, and lower memory usage for large lists.

🔬 Measurement: How to verify the improvement
Use React Developer Tools Profiler. Record a session while scrolling or triggering state updates in the Tribe feed. Observe that TribePostListItem components do not re-render unless their specific post prop or interactions change.
