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).

plain set(1) / get() -> 1

setOpaque(2) / getOpaque() -> 2

setRelease(3) / getAcquire() -> 3

setVolatile(4) / getVolatile() -> 4

compareAndSet(4, 5) succeeded -> true, second compareAndSet(4, 6) succeeded -> false (expected false - value is 5, not 4, by the second call)
