ArrayRule class final

Validates array length and per-element schema constraints.

When prefixItems is present in a schema, items must only apply to elements beyond the prefix. The itemsStartIndex parameter controls this: the items schema is applied only to elements at indices ≥ itemsStartIndex. When itemsStartIndex is 0 (the default, used when no prefixItems is present), items applies uniformly to all elements, which is the pre-2020-12 behaviour.
