refactor: reorganize code structure and optimize modular design

- Remove src/common/address_lookup.rs and tip_cache.rs to simplify common modules
- Move protocol-specific utility functions from trading/ to instruction/utils/
- Refactor utility functions for PumpFun, PumpSwap, Raydium AMM V4, and Raydium CPMM
- Consolidate constant definitions by inlining seeds and accounts modules into respective utility files
- Update all import paths to ensure code consistency
- Optimize trading parameter construction and executor logic
- Improve address lookup cache and nonce management mechanisms
