v7.8.3: Auto-upgrade WolfNet during setup.sh

- setup.sh now checks if WolfNet has updates available when already installed
- Compares local git HEAD against origin/main for the WolfScale repo
- If newer code exists: pulls, rebuilds, replaces binary, restarts service
- Works for both running and stopped WolfNet states
