Description

Currently, the integration test utilities in integration-tests/tests/utils/docker_utils.py use docker ps with name prefix matching to validate running containers (see list_running_containers_with_prefix()).

Proposed Enhancement

Switch to using docker compose ps with the project name specified. This approach would provide:

1. Exact container list: Query the precise set of containers managed by the docker compose project, eliminating false positives from containers with similar name patterns
2. Exit status validation: Check for containers that should have exited at certain stages of the package run, enabling more comprehensive lifecycle validation
3. Better integration: Align with docker compose's native container management and project scoping
