- Default upstream auto-detected from system resolver (scutil/resolv.conf)
instead of hardcoding Google 8.8.8.8. Falls back to Quad9 (9.9.9.9).
- Single scutil --dns pass for both upstream detection and forwarding rules
- Linux: reads backup resolv.conf if current only has loopback
- Service start/stop now couples DNS config (install on start, uninstall on stop)
- Install script for one-line binary install from GitHub Releases
- GitHub Actions release workflow: builds for macOS/Linux x86_64/aarch64
