Usage:
  ./manage.sh [--dry-run] validate
  ./manage.sh [--dry-run] deploy core
  ./manage.sh [--dry-run] deploy SERVICE [SERVICE ...]
  ./manage.sh [--dry-run] purge-legacy

`deploy SERVICE` deliberately uses --no-deps. It never recreates unrelated
containers. `deploy core` is the complete Athena runtime and may start missing
dependencies. Hermes und portable Fach-MCPs gehören nicht zu Athena.
