feat: integrate template awareness into AI assistant

- Add template configurations with file structures and conventions
- Update AI route handler to include template context in system messages
- Pass template type through AIChat component
- Add template-specific run commands
- Enhance AI responses with project structure knowledge
- Move hardcoded run commands from navbar/run.tsx to templates/index.ts

This improves the AI's understanding of different project templates (React, Next.js, Streamlit, Vanilla JS) and enables more contextual assistance based on the project type.
