✅ COMPLETE: Fix chat system to use AI-powered responses

- FIXED chat system still using hardcoded ai-responses.js fallbacks
- REPLACED generateContextualResponse call with generateChatAIResponse
- ADDED generateChatAIResponse method for chat interface
- NOW BOTH systems (step-by-step AND chat) use server-side AI
- ADDED debugging logs to track request/response flow
- Updated cache-busting version for immediate testing

Chat responses for 'thrust?' should now be contextual and educational!
