Move the logic for building user content, including topic selection and recent prompts avoidance, into a shared function in generic.py. Update openrouter.py and openwebui.py to use this new function instead of duplicating code.
Add retry logic and fallback mechanism to prompt generation. When OpenWebUI
fails, the system now attempts a second try before falling back to OpenRouter.
Proper error handling and logging have been added throughout the prompt
generation flow to ensure more reliable operation.
