refactor(core): optimize state management and component rendering performance

Improve application stability and performance by optimizing Zustand store usage, implementing memoization patterns, and introducing persistent authentication. - **State Management**: - Refactor Zustand selectors to use `useShallow` and `getState()` to prevent unnecessary re-renders and infinite loops in hooks. - Implement `persist` middleware for `authStore` to maintain user sessions across restarts. - Introduce `buildStateCached` in `themeStore` to reduce redundant theme object computations. - **Performance & Rendering**: - Implement `useMemo` for stable object/array references in `ImageGallery` and list components to prevent expensive re-renders. - Replace inline arrow functions with `useCallback` in complex screens like `ChatScreen` and `MessageListScreen`. - Optimize `FlashList` usage by providing stable `key` and `extraData` props. - **Architecture**: - Decouple unread count fetching by introducing `useUnreadCountQuery` (React Query) for better caching and synchronization. - Add `useChannels` hook to centralize channel data fetching. - Refine `SessionGate` logic to allow immediate rendering of authenticated users while verifying in the background.
