Code Review - Summary

What was done

This PR removes the retryWithBackoff utility function and its usage in the socket server's CONNECTION_STATE event handler. The change simplifies the code by removing retry logic for 5xx errors when requesting connection state from the API.

Positive Points

• Clean removal of unused code - the entire retryWithBackoff.ts file is properly deleted
• Simplifies the CONNECTION_STATE handler by removing complexity
• Maintains the core functionality while reducing code overhead
• Good commit message following conventional commits format

Issues Found

• Critical: Removing retry logic without error handling could cause connection state requests to fail permanently on temporary API issues
• Important: No alternative error handling strategy is implemented to replace the retry mechanism
