Fix PowerShell window closing: wrap in try/catch/finally

- Remove $ErrorActionPreference = "Stop" (caused unhandled exits)
- Write-Err now throws to outer catch (shows error, stays open)
- finally block always pauses with Read-Host before closing
- npm output piped through Write-Host to prevent stream errors
