Detailed Description

C++17-compatible atomic wait/notify implementation.

Provides wait() and notify() operations for std::atomic that work in C++17, with automatic fallback to std::atomic's built-in versions when available in C++20.

This implementation uses mutex + condition_variable with optimizations:

• Short spin-wait before blocking (cache-friendly)
• Efficient waiter management
• Proper memory ordering guarantees
