LRU Cache Project

This project implements a thread-safe LRU cache in modern C++ with:

• O(1) get() and put() using std::unordered_map and std::list
• std::shared_mutex for concurrent readers/writers
• Google Test coverage for correctness and thread safety
• A simple TCP server exposing SET key value and GET key commands
• Google Benchmark harness for performance measurement
