* restart: Match Docker Compose semantics
Change `cf restart` from doing `down + up` to using `docker compose
restart`, matching the Docker Compose command behavior.
This provides command naming parity with Docker Compose. Users who want
the old behavior can use `cf down mystack && cf up mystack`.
- Update restart implementation to use `docker compose restart`
- Remove traefik regeneration from restart (no longer recreates containers)
- Update all documentation and help text
- Remove restart from self-update SSH handling (no longer involves down)
