Add a new navigator-vm library crate that boots k3s inside a libkrun microVM, accessible from the host via gvproxy port forwarding. Key components: - FFI bindings to libkrun C API (krun_create_ctx, krun_add_net_unixgram, etc.) - VmConfig with gateway() preset for k3s and custom exec mode - gvproxy integration: virtio-net via unixgram, DHCP, native HTTP port forwarding - gateway-init.sh: PID 1 init script with DHCP via udhcpc, mounts, k3s exec - build-rootfs.sh: builds Ubuntu 22.04 arm64 rootfs with k3s + busybox-static - Kubeconfig auto-extraction to ~/.kube/gateway.yaml - CLI integration as 'ncl gateway' with --exec, --port, --net flags - macOS codesigning and DYLD_FALLBACK_LIBRARY_PATH in ncl wrapper
