Subject: [PATCH] Add Docker support with multi-stage build

Enable output: standalone in next.config.ts so Next.js produces a
self-contained server bundle in .next/standalone. Multi-stage Dockerfile
(deps -> builder -> runner) on node:20-alpine keeps the final image
minimal; app runs as a non-root user for security. .dockerignore
excludes node_modules, .next, .env files, and editor tooling.

To build and run:
  docker build -t portfolio .
  docker run -p 3000:3000 portfolio
