Some command errors on Windows (setup - xargs, ls position commands)

During the :setup command, Conductor goes to list relevant files. While many linux commands are defined as aliases in Windows to the correct cmdlet, xargs isn't one of them.

For my brownfield project, setup continued fine despite this, and it still had reasonable recommendations for product scope and tech stack. It was likely able to infer from reading package.json and firebase.json after this failed command.

Asking Gemini to convert the command into valid Powershell generates
git ls-files --exclude-standard -z -c -o | ForEach-Object { $_ -split "0" } | Where-Object { $_ } | ForEach-Object { Split-Path $_ -Parent } | Sort-Object -Unique`
which appears to create the correct formatted output.

I'd recommend having setup check for the OS (perhaps attempt cat /etc/os-release and if it fails then host or be very fancy with [System.Runtime.InteropServices.RuntimeInformation]::OSDescription) and either hardcode a Windows equivalent or just let gemini translate on the fly.

Start at the :setup command and trace where the shown git ls-files ... | xargs ... pipeline is invoked. Compare its behavior on Windows PowerShell with the reported file-listing output, then verify that setup completes without the xargs error and still discovers relevant files.
