feat: refactor trading architecture with unified framework
- Add unified TradeExecutor interface and protocol abstraction - Refactor PumpFun/PumpSwap into adapter pattern - Introduce TradeFactory for multi-protocol support - Add parallel execution and unified parameter system - Include Raydium protocol support and log parsing - Simplify codebase structure and improve maintainability
