fix(bsk): fix Windows self-update failing to replace binary

Two issues prevented the detached update helper from completing:

1. Only CREATE_NO_WINDOW was set — the child cmd.exe process was still
   attached to the parent console session and got killed when the
   terminal closed. Add CREATE_NEW_PROCESS_GROUP to fully detach it.

2. `timeout /t 1 /nobreak` requires a console and fails silently in a
   no-window context, causing the retry loop to spin with no delay.
   Replace with `ping -n 2 127.0.0.1` which works in any environment.
