auto	ginger::get_thread_pool () -> thread_pool &
	Convenience accessor returning a singleton thread pool.

Detailed Description

Minimal header-only thread pool for C++17.

Owns a fixed set of worker threads that process tasks from a shared queue. Tasks are enqueued via enqueue() which returns a std::future to the result.

Usage:

ginger::thread_pool pool;
auto future = pool.enqueue([] { return 42; });
int result = future.get();

The destructor waits for all pending tasks to finish and joins all worker threads. It is safe to destroy the pool while tasks are still running — remaining tasks are abandoned.
