Codescribe e7040bd9f9 feat: add VPN DNS split routing ...

Implement VPN DNS discovery and split routing for intercept mode:
- Discover VPN DNS servers from F5 BIG-IP, Tailscale, Network
  Extension VPNs, and traditional VPN adapters
- Exit mode detection (split vs full tunnel) via routing table
- Interface-scoped pf exemptions for VPN DNS traffic (macOS)
- Windows VPN adapter filtering with routable address check
- AD domain controller detection with retry on transient failure
- Cleanup of stale exemptions on VPN disconnect

Squashed from intercept mode development on v1.0 branch (#497).
