"""Tests for the Slack plugin's interactive_setup wizard.

These cover the home-channel save logic that previously lived in
``hermes_cli/setup.py::_setup_slack`` before the Slack adapter migrated to a
bundled plugin (#41112). ``interactive_setup`` lazy-imports its CLI helpers
from ``hermes_cli.config`` (get_env_value / save_env_value / remove_env_value)
and ``hermes_cli.cli_output`` (prompt / prompt_yes_no / print_*), so we patch
those source modules.
