TrueNAS custom apps cannot build: the main compose's 'build: .' (plus
relative .env/bind mounts) fails app 'up'. Added a GitHub Actions
workflow publishing ghcr.io/fez5587/momentum-app on every master push,
and deploy/docker/truenas-compose.yml — a pull-only variant with
dataset host-paths, inline environment (secrets as <FILL-ME>
placeholders, current validated strategy knobs pre-filled), and the
same healthchecks. Validated with docker compose config.
