chore(v2): vendor dependencies for offline/China builds

go mod vendor pins onnxruntime_go v1.12.1, Gio and the rest into v2/vendor so go run/build work without hitting proxy.golang.org (blocked/slow in China). Verified: CGO_ENABLED=1 go build -mod=vendor ./internal/spike and GOOS=windows go build -mod=vendor ./internal/ui both pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
