- try/finally（无 except）：正常/异常路径都执行 fbody，异常时 finally 后 重新传播（done+br exit）；finally 内暂不支持 await - 异常消息：帧加 msg 槽（i8*，index 4），raise X(msg) 存消息，await 传播， coro_exception_msg 查询 - raise 支持自定义异常类（exception_registry 码），多 except 匹配子类码 - 帧池复用：per-type free-list 全局池，create 弹池/空则 malloc，coro_destroy 回池（帧头部存 next），避免反复 malloc/free - 修复 ast.walk 传 list 崩溃（finalbody/For body） - CoroTest 验证：finally 执行、MyError exc=100 msg=boom msg、3 次循环池复用
