fix(chart): rewrite suggestion logic with better error handling

- Remove conflicting tool approach, use direct JSON
- Add fallback: extract numbers from regex if AI fails
- Add debug section to show what content was analyzed
- Be more lenient: any 2+ numbers = valid chart
- Better error messages
- Add console logging for debugging
