fix(hermes): create custom sendMessageWithCustomHistory function

- Add sendMessageWithCustomHistory function to handle intro generation
- Fix TypeError: sendMessageWithHistory is not a function
- Custom function allows intro to use different system prompt than conversation
- Maintains streaming response for real-time intro generation
- Fixes intro message generation with proper API call handling
