/**
 * Local Docker build helper.
 *
 * Reads version pins from config/defaults.json and invokes `docker build`
 * with the correct --build-arg values so developers never need to remember
 * (or hardcode) version strings.
 *
 * Usage:
 *   node scripts/docker-build.mjs                      # defaults
 *   node scripts/docker-build.mjs --tag my-tag          # custom tag
 *   node scripts/docker-build.mjs -- --no-cache         # extra docker args
