The `main.py` check is not strict enough

[Chaoses-Ib]

Expected Behavior

Importing comfyui from user's main.py works fine.

Actual Behavior

Using main.py will make comfyui change the base path to the root of comfyui, not the current directory. This can lead to confusion, e.g. https://github.com/Chaoses-Ib/ComfyScript/issues/65

https://github.com/hiddenswitch/ComfyUI/blob/3e91f98aa22fb620f339e0602f059bfa1fb5bf6d/comfy/cmd/folder_paths.py#L83-L84

Steps to Reproduce

I only have the code to reproduce in ComfyScript:

main.py:

from comfy_script.runtime import load
load("comfyui")
from comfy_script.runtime.nodes import Checkpoints

print(list(Checkpoints))
# No models from the `models` folder in the working directory

i am addressing this now. the painful part of upstream is that it has a bunch of statics everywhere. I will replace them with contextvars in a later update, but a patch to make this not occur will happen shortly.
