/**
 * Backward-compatibility shim. New code should construct
 * ABJ_404_Solution_Functions directly with explicit MbStringAdapter and
 * RegexHelper instances (or depend on those adapters alone if the
 * kitchen-sink Functions surface is not needed).
 *
 * Wires Functions to the Mb variants of MbStringAdapter and RegexHelper so
 * the polymorphic primitives use the mbstring extension. The class itself
 * has no extra behavior beyond adapter selection - the legacy inheritance
 * pattern (abstract Functions + concrete subclass per platform) has been
 * replaced with composition (Functions holds the adapters).
