Summary

Works entirely within JavaScriptCore, concentrated on ECMA-402 internationalization builtins — `BigInt` argument support in `Intl.PluralRules.select`/`selectRange` and separator handling in `Intl.DurationFormat` — alongside a fix for default derived constructors incorrectly observing `Array.prototype[@@iterator]`. The pattern is spec-conformance work rather than security or hardening: correcting observable behavior to match the ECMAScript and ECMA-402 specifications. Of the three, only the derived-constructor change touches core object-construction semantics; the rest sit in the Intl surface.
