- Merge BuyParams and SellParams into unified SwapParams structure
- Add USD1 token pool support with related constants and configurations
- Refactor trade executor by combining buy_with_tip and sell_with_tip into swap method
- Update all protocol instruction builders to support new parameter structure
- Standardize ATA creation/closing parameter naming conventions
- Update example code to use new API interfaces
- Optimize trading logic with automatic direction detection based on input token type
