refactor: Refactor SDK core architecture and trading parameter system

- Refactor SolanaTrade main class structure with improved modular design
- Refactor trading parameter system: BuyParams/SellParams -> InternalBuyParams/InternalSellParams
- Remove deprecated PriorityFee and related utility functions
- Add SwqosSettings to replace legacy SwqosConfig
- Add comprehensive technical documentation:
  • Address Lookup Table usage guide (EN/CN)
  • Nonce Cache mechanism documentation (EN/CN)
  • Trading Parameters documentation (EN/CN)
- Refactor all example code to adapt to new API interfaces
- Optimize public API design and code comments
- Clean up redundant utility functions and type definitions
