REM ============================================================
REM Orchestrated (noninteractive) staging mode.
REM Entered only when the first argument is --orchestrated; the legacy
REM interactive flow above is untouched. Operates on a private staging
REM copy only: no prompts, no network, no config edits, no uninstaller
REM generation, no pause and no self-delete. Deletes nothing; the caller
REM must pass a free staging directory as the cwd.
REM Usage: setup_windows.bat --orchestrated <asi|proxy> [--exename <name>]
REM Requires env SUSEMI_ORCH_STAGE=1 and OptiScaler.dll in the cwd.
REM Emits one ASCII machine line (status=...) first, then a human line.
