test(lifetime): 新增 NewLifetimeAsyncTest 负向工程;测试项目 main 统一为 export def main() -> int
- NewLifetimeAsyncTest:协程体里的 new heap slife 必须报 LifetimeError(fail-fast 的回归覆盖),已挂进 ESCAPE_PROJECTS / NEGATIVE_PROJECTS / NEGATIVE_PROJECT_NAMES 与 README。 - NewLifetimeTest / NewLifetimeFreeTest 的 main 改为 export def main() -> int,并删掉多余的 t/c 导入(与 FuncTest / FormatStringTest / NewTest 一致)。

# 负向工程(**应当编译失败**,对照工程:NewLifetimeTest)
|

#
|

# 协程体(async)里的 `new heap slife` 必须被拒:AsyncGenMixin 的状态机会把 body 拆成多个
|
||||
# state 块并多次转译,编译器无法确定释放点 → CallGenCtor._translate_new_expr 在此 fail-fast
|
||||
# (LifetimeError,提示改用 `new heap hlife` 或把分配挪进普通函数)。
|
||||
#
|
||||
# 说明见 Debugger/ownership-and-new.md §4.2 的「async 的收口」。
|
||||
# `new stack`(帧内 alloca,本来就无需释放)与 `new … hlife`(自行管理)不受这条约束影响。
