--wait-for-client no longer waits.

In 2025.0.0, using --wait-for-client doesn't wait anymore when used from the integrated terminal.

I'm running a devcontainer, I've got a venv in my workspace and an empty test.py file.

From the integrated terminal I run this...

$ which python3
/workspaces/my-project/.venv/bin/python3
$ python3 -m debugpy --wait-for-client --listen 5678 test.py
$ 

...and the program terminates. It shouldn't since I've asked it to wait.

From a terminal I've opened up via docker exec'ing to the container I run the equivalent...

$ source ./.venv/bin/activate
$ python3 -m debugpy --wait-for-client --listen 5678 test.py
0.00s - Debugger warning: It seems that frozen modules are being used, which may
0.00s - make the debugger miss breakpoints. Please pass -Xfrozen_modules=off
0.00s - to python to disable frozen modules.
0.00s - Note: Debugging will proceed. Set PYDEVD_DISABLE_FILE_VALIDATION=1 to disable this validation.

...and I get the behavior expected.

If I downgrade to 2024.14.0 I get the proper behavior in the integrated terminal.

The two main versions I believe might be important are

debugpy 1.8.12
Python 3.12.3

Let me know if you need anything else. In the meantime I'm downgrading to 2024.14.0

I realized I also had other problems with stepping now working as usual as well very similar to #544, and also in a gunicorn multi process setup. I downgraded debugpy back to an earlier version 1.6.7 and disabled this extension which solved these problems.

It seems this extension isn't even installed with the version of debugpy, which also explains why I had never noticed this extension prior...

Hope this helps someone.
