Adds a dedicated cleanup step for Docker containers and improves log directory handling before running integration tests.

• Introduce clean-containers target and hook it into each test target
• Add argument validation and directory reset in copylogs target

integration/Makefile:58

• [nitpick] Consider renaming the variable target to uppercase (e.g., TARGET) or a more descriptive name like LOG_DIR to avoid confusion with file targets and improve clarity.

	if [ -z "$(target)" ]; then echo "target directory not specified"; exit 1; fi

[Copilot]

Add clean-containers to the .PHONY declaration so Make treats it as a phony target and avoids conflicts with files of the same name.
