Fix confirmations.

- This fixes what it means to get confirmations in GC. Prior to this they had just been accidentally unwired as part of all of the refactorings to turns + to server/core.
  - The key piece of this is that we wrap the onConfirm in the gemini stream hook in order to resubmit function responses. This isn't 100% ideal but gets the job done for now.
- Fixed history not updating properly with confirmations.
