Juan DenisandClaude Fable 5 783b0876bd Build the frontend stage natively in multi-arch Docker builds
The release workflow builds linux/amd64,linux/arm64 via buildx + QEMU on
an amd64 runner, so the frontend-builder stage ran `npm ci`/`npm run
build` under emulation for arm64 -- 20-40 minutes when it did not hang
outright. Its output (frontend/dist) is static, arch-independent assets,
so pin the stage to $BUILDPLATFORM: buildx runs it natively, once, shared
by both platform images. Final images are unchanged.

# ============================================
# ServerKit Dockerfile - Single Container
# ============================================
# This Dockerfile creates a single container with both
# frontend and backend. Good for simple deployments.
#
# For production with separate containers and nginx,
# use docker-compose.yml instead.
#
# Build: docker build -t serverkit .
# Run: docker run -d -p 5000:5000 --env-file .env serverkit
# Override the internal backend port with SERVERKIT_BACKEND_PORT if needed.
# ============================================
# Stage 1: Build Frontend
# --platform=$BUILDPLATFORM: dist/ is static JS/CSS (arch-independent), so this
# stage always runs natively on the build machine — never under QEMU, where an
# emulated `npm ci` takes 20-40 min (or hangs) during multi-arch release builds.
