🔀 A thread pool, from scratch

Task queue + condition_variable + std::future, with deadlock-free graceful shutdown.

Build a working thread pool / executor: a thread-safe task queue, condition_variable signalling, submit() returning std::future, and the subtle shutdown protocol that drains tasks and joins workers without lost-wakeup deadlock. Real concurrency, runnable.
