`asyncio.get_event_loop` raises error instead of spawning new loop when no loop is running.

>>> import uvloop, asyncio
>>> asyncio.get_event_loop()
<_UnixSelectorEventLoop running=False closed=False debug=False>
>>> uvloop.install()
>>> asyncio.get_event_loop()
Traceback (most recent call last):
  File "<python-input-4>", line 1, in <module>
    asyncio.get_event_loop()
    ~~~~~~~~~~~~~~~~~~~~~~^^
  File "/usr/local/lib/python3.13/site-packages/uvloop/__init__.py", line 206, in get_event_loop
    raise RuntimeError(
    ...<2 lines>...
    )
RuntimeError: There is no current event loop in thread 'MainThread'.

As you can see in the snippet above when run on un-patched asyncio it's returning a new loop. But uvloop raises error because of the method override which was not there in previous version inheriting the original new loop spawning function.

在安装了 uvloop 的情况下重现 Python 代码片段，然后检查 uvloop/init.py 中链接方法附近的 get_event_loop 覆盖实现。将其行为与未打补丁的 asyncio 进行比较；当在没有正在运行的 loop 时调用 asyncio.get_event_loop() 在两种情况下都具有预期行为时，该 issue 就完成了。
