refactor: optimize trading execution architecture and add wSOL management

- Simplify TradeExecutor interface by integrating middleware and swqos clients into params
- Refactor parallel execution module with dedicated buy/sell execute functions
- Add SOL wrapping/unwrapping functionality for wSOL management
- Remove redundant parameter passing in sell operations
- Delete example main.rs file
- Optimize transaction building with integrated parameter structures

BREAKING CHANGE: TradeExecutor interface simplified, middleware and swqos_clients now passed through params
