fix: improve panic recovery in main function

- Move panic recovery defer to the beginning of main function to ensure it can catch panics from all subsequent function calls

- Remove unused setupErrorRecovery function

- Add explanatory comment for the defer placement

This change ensures proper error handling throughout the entire program execution, rather than just within the setupErrorRecovery function scope.
