Description: Summary by CodeRabbit Bug Fixes Fixed template-string evaluation/interpolation order and surrogate-preserving literals; improved loop-target line attribution and no-op anchoring; clarified dictionary lookup behavior for built-ins vs subclasses. Performance Expanded constant-folding (subscripting, string/bytes/concat/repeat) and optimized large collection literal emission and jump/no-op threading. Features Improved generic class/type-parameter initialization ordering and conditional-annotation bookkeeping. Tests Added regression tests covering these behaviors.
