feat(examples/langgraph-python-threads): use intelligence composite image (CopilotKit#4120)

## Summary

Replaces the four separate intelligence containers (`db-migrations`,
`app-api`, `realtime-gateway`, `thread-culler`) in the
langgraph-python-threads example with a single `intelligence` composite
container that runs all of them under `s6-overlay` supervision. Compose
file drops from six services to three (`postgres`, `redis`,
`intelligence`). README updated to match.
