- Change default server listen addresses to empty string (listen on all interfaces including IPv6)
- Add short hostname matching fallback in host lookup API to handle FQDN vs short name mismatches
- Implement retry loop (30s) in both Windows and Linux/macOS installers for registration verification
- Fix lint errors: remove unnecessary fmt.Sprintf and nil checks before len()
This resolves the 'Installer could not yet confirm host registration with Pulse' warning
by addressing timing issues, hostname matching, and network connectivity.
