Pull Request Overview

This PR fixes a bug where SDK initialization could fail or remain uninitialized in React 17, causing an infinite loading state. The issue was caused by a circular state dependency where store state was being read and then unnecessarily written back in the same effect.

Key Changes

• Removed the storeState useMemo that was creating a circular dependency
• Removed storeState from the useDeepCompareEffect dependencies and update call
• Stores are now properly managed exclusively through the useSendbird hook's actions
