"""Tests for the Matrix plugin's interactive_setup wizard home-channel flow.

The interactive_setup wizard lazy-imports its CLI helpers from
``hermes_cli.config`` (get_env_value / save_env_value / remove_env_value),
``hermes_cli.cli_output`` (prompt / prompt_yes_no / print_*), and
``tools.lazy_deps`` (mautrix ensure). We patch each at its source module so
the wizard runs without touching pip or the network. Covers the home-channel
clear-on-blank behavior added in the follow-up to PR #58421.
