Implements full class support: prototype-chain-based inheritance on JsObject, class/extends/super/static/instanceof keywords, parser and VM execution for class declarations and expressions, super() constructor calls and super.method() dispatch via dedicated SuperInfo fields (not user-observable properties), and instanceof operator with prototype chain walking. Includes depth guards, Box<JsValue> in RuntimeError::Thrown to satisfy clippy result_large_err, and 11 JS262 conformance tests. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
