Run pytest and inspect tests/test_workspacebuilder.py around test_environment_variables, then review the libtmux EnvironmentMixin.show_environment signature named in the traceback. Confirm the compatibility issue and verify that pytest passes after the test and implementation agree on the environment-variable lookup.
