b701fac656This commit introduces a mechanism for validators to return early once the validation outcome is determined, rather than evaluating all child validators. The ShortCircuit validator evaluates validators sequentially and stops at the first failure, similar to how PHP's && operator works. This is useful when later validators depend on earlier ones passing, or when you want only the first error message. The ShortCircuitCapable interface allows composite validators (AllOf, AnyOf, OneOf, NoneOf, Each, All) to implement their own short-circuit logic. Why "ShortCircuit" instead of "FailFast": The name "FailFast" was initially considered but proved misleading. While AllOf stops on failure (fail fast), AnyOf stops on success (succeed fast), and OneOf stops on the second success. The common behavior is not about failing quickly, but about returning as soon as the outcome is determined—which is exactly what short-circuit evaluation means. This terminology is familiar to developers from boolean operators (&& and ||), making the behavior immediately understandable.
