Implement both loop types across the full stack: tokenizer (`In` keyword), AST (`ForBinding`, `ForInStmt`, `ForOfStmt`), parser (refactored `parse_for()` with `in`/contextual `of` detection), object model (`enumerable_keys()`), and interpreter (per-iteration lexical scoping for let/const, `assign_to_target()` for member/computed-member LHS patterns, var hoisting). for...of supports arrays and strings natively; non-iterable types throw TypeError. Full iterator protocol deferred to Symbol support. Includes 24 parser tests, 45 interpreter tests, and 6 JS262 fixtures. Promotes the existing for-in-loop known_fail to pass.
