The chat_completions and transport-parity Mistral tests pinned the
same branch with different reasoning_config shapes ({effort:none} vs
{enabled:False, effort:none}) — behaviorally identical since effort
short-circuits first, but the drift reads as a semantic difference.
Align both to the explicit form. Also scope the port-guard comment to
the try/except shape it actually shares with hermes_cli/models.py.
