[Bug]: Unable to locate Codex CLI binaries. Ensure @openai/codex is installed with optional dependencies.

Reproduce the GPT-agent flow on Windows 11 and start from the server's agent startup error and the logged cp/rm failures. Trace how the Codex CLI binaries are located and how checkpoint commands run; done means the agent starts without binary-location or shell-command errors and the Polyscope menu option is addressed.

Platform

Windows

Operating system version

Windows 11

System architecture

Intel (x86)

PolyScope Version

latest

Bug description

Codex on windows is unable to find binaries, and there is no option to set the path to use.

There is also no Polyscope option in the menubar.

Steps to reproduce

1. Set agent to GPT
2. Type anything
