fix: Exclude Umbrix processes from VPN routing

- Uncommented process exclusion rule for desktop platforms
- Changed process names from Hiddify to Umbrix
- Added 'Umbrix Start.exe' to handle renamed launcher
- Prevents routing loops when Umbrix routes its own traffic

Process names excluded:
- Umbrix, Umbrix.exe (main app)
- Umbrix Start.exe (launcher)
- UmbrixCli, UmbrixCli.exe (CLI utility)
