🔧 ADD: CPU/Computer responses and server improvements

- Added comprehensive CPU/computer responses in ai-responses.js
- Added contextual CPU detection logic in script-new.js
- Fixed server encouragements to be topic-specific
- Improved pneumatic tool responses
- Added debugging to troubleshoot response generation
- Server now provides contextual encouragements based on question content
