Reduce allocations from callers (#54), add new unit tests, and fix existing -race unit test failures

What's Changed

• Reduce allocations per lock request (#52) — replaces goroutine-per-lock deadlock detection with time.AfterFunc + sync.Pool, cutting allocations from 4 to 2 per lock/unlock cycle (~40% throughput improvement).
