Subject: [PATCH] fix(install): add DTVEM_ROOT support to PowerShell installer

The PowerShell install script now respects the DTVEM_ROOT environment
variable, matching the behavior of the bash installer. Users can set
this variable before running the installer to use a custom installation
directory.

Closes #175
