refactor: optimize component rendering with memoization and improve state management

- Added memoization to ChatHistoryPanel, ChatMessageList, and TaskBoard components to prevent unnecessary re-renders.
- Refactored HomePage to utilize useMemo for derived state calculations, enhancing performance.
- Updated main.tsx to conditionally render React.StrictMode based on the environment.
- Improved chat and channel store hooks to allow for selector functions, enhancing flexibility in state selection.
- Enhanced streaming message handling in chat store to manage pending deltas more effectively.
- Refactored LoginPage to include animated decorations for improved user experience.
- Implemented lazy loading for routes in the router to optimize initial load time.
