fix: address the eighth review round

`docker-compose.ollama.yml` builds the app, realtime server, and migrator from
source, which I had missed:

- The Ollama upgrade block ran `pull` then `up -d`. That refreshes only the
  Ollama and Postgres images and leaves every Sim service on its old build. It
  is a checkout plus `build --pull` now.
- The source rollback showed only the local file and no profile; the Ollama
  stack needs both.
- Dropped the Ollama mention from the `COMPOSE_FILE` comment above, since that
  stack is covered by its own profile-aware commands rather than the CLI.
