feat: add transaction confirmation wait option and parallel execution optimization

- Add wait_transaction_confirmed parameter to all trading methods
- Support async transaction sending without waiting for confirmation for better performance
- Optimize parallel execution logic to return on first successful transaction
- Fix direct priority_fee modification issue
- Improve error handling and resource management
- Update all example code to support new parameter
