[Regression] Codex thinks i am on Linux

What version of Codex is running?

0.53.0

What subscription do you have?

PRO

Which model were you using?

_No response_

What platform is your computer?

Microsoft Windows NT 10.0.26100.0 x64

What issue are you seeing?

`codex --yolo` used to make codex run in windows, giving it all the tools available here.
Now it thinks it is running on linux (probably wsl?) making all tools unavailable and working with it is also slow due to the filesystem boundary between wsl and windows.

What steps can reproduce the bug?

• Be on windows
• Install latest codex (53)
• `codex --yolo`
• Tell it to compile something
• Can't because it doesnt see eg. dotnet

What is the expected behavior?

Run under windows (like in 0.52) and be able to use windows tools

Used to work in 0.52
