Swarm tries to install Python things outside venv

[JS3910]

Expected Behavior

I expect installation of fresh SwarmUI to work as intended.

Actual Behavior

When SwarmUI is trying to install the Comfy backend, it's not using any venv so on a system where pip is configured to refuse any install commands outside a venv (which should be all sane/secure python installations) it errors out.

Obviously, neither SwarmUI nor Comfy have any business or use from installing site-wide Python packages, so this is clearly a bug in the installer.

Steps to Reproduce

Set environment variable PIP_REQUIRE_VIRTUALENV=true and try to install with the normal installer script. This is on Windows, have not tested the Linux install script to see if it has the same issue.

the Windows install uses a special embedded python, which is not a venv but rather a more intensely localized installation than even that. The linux install just uses a standard venv.

Put file pip.ini in SwarmUI\dlbackend\comfy\python_embeded with rows:

[global]
require-virtualenv = false

It would not install in the global python.
