Previously, OmniRoute unconditionally injected thinking: {type: 'adaptive'} and
output_config: {effort: 'high'} for Claude Opus 4.7 in Claude Code client requests.
This caused Claude Max 5h quota to drain in ~15 minutes.
Now checks the original client body: if thinking or output_config are explicitly set
(even to null or a different value), the injection is skipped. Users can opt-out by
sending thinking: null or output_config: {effort: 'low'}.
