On Windows, native Python extensions such as _bcrypt.pyd are loaded as
DLLs by any running hermes process. When the installer tries to recreate
the venv (Remove-Item -Recurse -Force "venv"), Windows denies the delete
because the DLL is still mapped into the running process.
Add a taskkill /F /T /IM hermes.exe call before the Remove-Item so any
hermes process tree is stopped first, releasing the file lock. A short
sleep gives the OS time to unload the image before deletion proceeds.
This mirrors the existing force_kill_other_hermes() guard already present
in the --update flow (update.rs), applying the same pattern to the full
reinstall/repair path through install.ps1.
