Add a dedicated Node.js build stage to the agent Dockerfile to compile the desktop UI and embed its output into the Go binary. Copy the built UI into internal/agentui/dist before go build and make the Go build respect TARGETOS/TARGETARCH args for multi-arch builds. Also update agent/.dockerignore to exclude dist/, ui/dist/, and ui/node_modules/ to keep the image build context small and cache-friendly.
