Summary by CodeRabbit

Bug Fixes
- Improved network monitoring so it only stops when the system’s default IPv4/IPv6 next hops actually change (instead of reacting to timer events).
- Improved system network reporting by filtering out non-routable IPs and excluding the client’s own WireGuard overlay IPs from generated metadata.
Tests
- Added/expanded unit tests covering next-hop comparison behavior and the new address filtering/exclusion logic, including edge cases.
