feat: major refactor with calculation utilities and instruction optimization

- Add comprehensive calculation utilities for all protocols (bonk, pumpfun, pumpswap, raydium)
- Refactor instruction modules to reduce code complexity and improve maintainability
- Optimize trading parameters structure and enhance common utilities
- Separate calculation logic from trading modules for better code organization
- Update dependencies and module exports
