asmhatreandClaude Sonnet 5 ff183da163 atomics: Java Atomics and VarHandle companion code 
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).

asmhatre 32b8067ecf locks: synchronized vs ReentrantLock vs StampedLock companion code 
JMH throughput sweep (1-64 threads), 9:1 read-heavy @Group benchmark,
tryLock(timeout) deadlock-avoidance demo, and a JDK21-vs-JDK25 JEP 491
virtual-thread-pinning comparison. Also promotes LICENSE to repo root
now that a second module exists.
