_run_oneshot_from_args replaces three identical confirm+run_and_exit blocks
(main, fast chat, Termux fast cli); _default_to_chat reuses the existing
_set_chat_arg_defaults instead of a second attr table. Also restores the
'bare hermes profile' note as _profile_status's docstring.
The 604-line 14-way if/elif on profile_action becomes one _profile_<action>
handler each, with per-handler imports derived from the branch's free names.
main.py re-exports cmd_profile and _render_distribution_plan so existing
imports/monkeypatches resolve unchanged.
