AtomicLong/LongAdder/VarHandle counters benchmarked against the synchronized and ReentrantLock baselines from the locks module, a deterministic ABA race against a hand-rolled Treiber stack plus the AtomicStampedReference fix, and a VarHandle access-modes demo (plain/opaque/acquire-release/volatile).
