Describe the bug

Any operation that follows a symlink or junction fails with ERROR_UNTRUSTED_MOUNT_POINT (WinError 448) inside Warp. The same operations work in Windows Terminal or standalone PowerShell. Related to #8882 (same error code, but for CreateProcess).

This breaks pytest, which creates convenience symlinks in tmp_path directories and then crashes during cleanup when Path.resolve() hits this error. All tests pass but pytest exits with code 1.

To reproduce

In Warp:

$d = "$env:TEMP\symtest"
mkdir "$d\real" -Force | Out-Null
New-Item -ItemType SymbolicLink -Path "$d\link" -Target "$d\real"
Get-ChildItem "$d\link"
Remove-Item "$d" -Recurse -Force

Result:

Get-ChildItem: The path cannot be traversed because it contains an untrusted mount point. : 'C:\Users\user\AppData\Local\Temp\symtest\link'.

In Windows Terminal: same commands succeed.

Expected behavior

Symlink traversal works as in any other terminal.
