NetCtrl v2.1.4 - Windows Kernel Routing Suppression & Complete Block

What's Changed in v2.1.4

• Suppressed Windows Kernel IPv4 Forwarding:
  • Automatically disables Windows TCP/IP interface forwarding (netsh interface ipv4 set interface <name> forwarding=disabled and PowerShell Set-NetIPInterface -Forwarding Disabled) and sets IPEnableRouter = 0 on application launch.
  • Previously, if Windows IP routing was enabled in the OS registry (e.g. from legacy SelfishNet tools), the Windows kernel routed packets at the IP stack level independently of user-space packet dropping, causing blocked devices to still reach the internet. With kernel forwarding suppressed, NetCtrl maintains 100% exclusive Layer-2 drop and rate-limiting authority.
