Concise verbs: make up (dev build+run), make prod (pull published image),
make down (stop regardless of mode), make clean (down + drop local image).
Updates all docs and compose-file comment headers to match.
docker-compose.yml now builds from source (dev-forward: run your local changes);
docker-compose.prod.yml overrides it to pull ghcr latest (build reset via !reset).
Adds make compose-up / compose-up-prod / compose-down. Env, ports, and extra_hosts
stay defined once in the base file; the prod override only swaps build -> image.
