refactor: optimize instruction builders structure and improve code documentation

- Add structured comment sections with clear code organization
- Improve variable naming and account address calculation logic
- Update comments for better readability across all trading protocols
- Enhance code structure for PumpFun, PumpSwap, and Raydium protocols
