Multi-stage Dockerfile with three targets: - development (dev server on :5173, used by docker-compose.yml) - build (runs npm run build, produces SvelteKit Node-adapter output) - production (self-contained node build server on :3000) Node base pinned to node:20.19.0-alpine3.21 for reproducible CI builds (Renovate will keep it current). docker-compose.yml now specifies target: development for the frontend so dev continues to use the dev-server stage. Without this, Docker would default to the last stage (production). Refs #497. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
