This commit introduces two main enhancements:
1. Adds an `auto_handle_wsol` parameter to `PumpSwap` buy/sell functions. When enabled, the SDK automatically manages the wrapping of SOL to WSOL and unwrapping back to SOL, simplifying client-side logic.
2. Enriches `PumpSwap` gRPC buy/sell events by parsing transaction instructions to include token mints and account addresses, providing more context for event consumers.
- 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
