"""Debug-mode flag.

When debug mode is on (``/debug on``), the trace logger additionally records
the full LLM request payload — system prompt plus full message history — into
the session trace (``.acli/traces/<session>.jsonl``). View with ``/log`` or
``/trace``.

The flag is armed at startup from persisted config (``configure_debug_log``)
and flipped live by the ``/debug`` command.
