Refactor error handling in WorkerService and SDKAgent

- Removed unnecessary logging for aborted sessions in WorkerService.
- Simplified the finally block in WorkerService by removing crash recovery logging.
- Cleaned up the try-catch structure in SDKAgent's startSession method, removing redundant error handling.
