Start with the feature/20962-implement-last-keyword-for-indexing-3 branch and the related hazelcast/hazelcast#20962 issue to understand the intended `n to last` array-range behavior. Compare that branch with the current JsonSurfer code and tests; the work is done when the requested range syntax is supported and its behavior is covered by the relevant tests.
