Fix SonarCloud/pylint warnings: unused imports, variables, and deprecated config

Remove unused imports (os in utils.py, tempfile/os in test_utils.py),
unused variable assignment in builder.py, unused arguments in deprecated
CLI stubs, and deprecated ignore-mixin-members pylintrc option.

Closes #377
