Summary

Fixes #832. On Windows, use Node's default command shell for Codex CLI availability checks and direct app-server launches, even when SHELL points to PowerShell. This selects npm's codex.cmd shim instead of a codex.ps1 shim that may be blocked by PowerShell execution policy.

Document the Windows launch behavior and add a Windows CI regression test that installs both fake shims, sets SHELL=powershell.exe, then verifies setup and a task run.

Verification

• node --test tests/process.test.mjs tests/runtime.test.mjs — 63 passed, 1 Windows-only test skipped on macOS
• npm run build — passed
• git diff --check — passed

The Windows regression test will run in the new windows-shim CI job.

Resolve Windows shims outside the checkout

When the plugin is run from an untrusted repository containing node.cmd or codex.cmd, shell: true delegates these bare command names to cmd.exe, whose normal lookup checks cwd before PATH; /codex:setup can therefore execute the repository's batch file as the user instead of the installed tool, and the changed app-server spawn does the same for codex. This newly exposes the SHELL=PowerShell users targeted by this change because PowerShell does not search the current directory by default, so resolve the intended shim from PATH to an absolute path before invoking it rather than relying on cmd lookup.
