Adds a JUnit test suite (GetVsGetReferenceTest, MergeRefreshTest, OptimisticLockTest, IdentityBatchTest, SequenceBatchTest, AllocationSizeSweepTest, BatchSizeSweepTest) so every surprising behavior described in the three companion posts has a reproducible test, alongside the original CommandLineRunner scenarios. Rewrites all three doc chapters and the README around the new experiments: the get()/getReference() same-session matrix, the merge()/refresh() experiments (including exactly when OptimisticLockException surfaces and a corrected LAZY-plus- cascade merge() result), and two new sweeps (allocationSize, batch_size) for batch inserts.
