Switched from requiring manual docker-compose up to testcontainers for automatic container management in tests. Key fixes: 1) Auto-detect Docker Desktop socket at ~/.docker/desktop/docker.sock, 2) Disable Ryuk with TESTCONTAINERS_RYUK_DISABLED=true, 3) Create shared tests/conftest.py with session-scoped postgres_container and redis_container fixtures, 4) Expose redis_url fixture for tests needing to create their own clients (avoids event loop issues), 5) Fix logger capture test - pytest disables loggers, need to set registry_logger.disabled=False
