feat: Add caching system and performance optimizations

- 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
