/**
 * Docker container extraction (spec-07 deferred follow-up: add-docker-container-graph).
 *
 * Parses Dockerfiles and docker-compose files together — they are cross-referential
 * (a compose `build:` resolves to a Dockerfile stage), so one extractor sees both —
 * and produces the normalized IacGraph that project.ts maps onto FunctionNode/CallEdge.
 *
 * Edge direction is dependent → dependency (like the rest of IaC), so depth-1 callers
 * of a base image answer "every stage/service rebuilt if this image moves".
 *
 * Static only: no `docker build`, no compose interpolation, no registry access.
 * Dynamic references (FROM ${ARG}, fully-templated build context) emit no edge.
