Allow disabling warning the model when AI credits are low

Describe the feature or problem you'd like to solve

I set -max-ai-credits=30 and the model kept getting worried about using all the credits

Proposed solution

Add an option to suppress whatever warnings are being injected to tell the model it is low on AI credits (or just remove it?).

Example prompts or workflows

No response

Additional context

I was testing with a local model, and passed --max-ai-credits=30 (because 30 is the minimum value allowed). The model kept saying "The user is warning me there are only 30 AI credits left so I must be very efficient with my responses".

I can't tell exactly what text was being injected for the model (because when I exported the session there was no such text in there - presumably the export is not complete), but it was happening on every turn. For a local model the credits are not relevant, but even with a cloud model I think I would rather this information be hidden so it won't potentially taint how the model is working. If it runs out, I can --resume with another value.

Comienza por el manejo de la opción --max-ai-credits y sigue el recorrido hasta donde se añaden las advertencias de pocos créditos al contexto del modelo. El issue no nombra ningún archivo ni prueba, así que primero identifica la ruta de inyección de advertencias y cualquier prueba de CLI relacionada; el trabajo estará terminado cuando los usuarios puedan suprimir estas advertencias mientras el límite de créditos existente y el comportamiento de reanudación sigan funcionando.
