Engine Updates

I haven't had time to backport all the engine changes to SMCA, I have added a few key features:

• The game now autosaves every turn.
• The LLM prompting has been restructured to avoid a bug in Cohere's API. Narration and LLM-driven decisions like Achiemvents should be more consistent now.
• I've added dynamic temperature control so the narrator should be less likely to get trapped in repetitive loops.
