- Add fast_fn module with global caches for PDA, ATA, and instruction operations - Implement memory-efficient caches using CLRU and parking_lot for thread-safe access - Optimize compute budget instruction generation with caching - Replace std::sync::Mutex with parking_lot::Mutex for better performance - Add dedicated caching for PumpFun PDAs and associated token addresses - Improve transaction building with batch signature optimization - Add new dependencies: clru, smallvec, parking_lot for cache infrastructure - Remove unused utility functions in pumpfun module - Enhance error messages for tip fee configuration validation
