"""The top-level parser's help text must not trip the wrong-profile fallback warning.

``main._apply_profile_override`` builds the parser (``top_level_value_flag_sets``) before it
re-homes the process to the sticky ``active_profile``; a help string that resolved the home through
``get_hermes_home()`` printed ``[HERMES_HOME fallback] ... wrong profile`` on every ``hermes``
command for users of ``hermes profile use`` (#112319, also reported in #112839).
