Add bytecode tests verifying identifier resolution produces correct register-backed locals, global lookups, argument indices, and environment lookups for eval/with/captured cases. Add runtime tests for destructuring assignment patterns with expression defaults: class expressions (named/anonymous), function expressions, arrow functions, nested destructuring, eval in defaults, MemberExpression targets with setter functions, and class name scoping.
