- 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

Linux:
- numa install: backs up /etc/resolv.conf, sets nameserver to 127.0.0.1
- numa uninstall: restores original /etc/resolv.conf from backup
- numa service start: installs systemd unit, enables + starts
- numa service stop: stops, disables, removes unit file
- numa service status: shows systemctl status
macOS: launchd plist (already working)
Both platforms: Restart=always / KeepAlive=true for crash recovery.
