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

The interactive_setup wizard 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_*); we patch those
source modules. Covers the home-channel clear-on-blank behavior added in
PR #58421 and extended in the follow-up.
