BIOS check fix, parallel downloads, shopfloor hardening

- Fix check-bios.cmd: replace parenthesized if blocks with goto labels
  (cmd.exe fails silently with if/else on network-mapped drives)
- Move BIOS check files to winpeapps/_shared/BIOS for reliable SMB access
- Add network wait loop before BIOS check in startnet.cmd
- Show firmware status in WinPE menu header (BIOS_STATUS variable)
- Add BypassNRO registry key to skip OOBE network requirement
- Refactor download-drivers.py with --parallel N flag (ThreadPoolExecutor)
- Set SupportUser AutoLogonCount to 3 in shopfloor unattend
- Add shutdown -a at start + shutdown /r /t 10 at end of Run-ShopfloorSetup.ps1
- Switch download-drivers.py from wget to curl for reliable stall detection
