feat: Add temperature monitoring and data export

- Implement TemperatureMonitor (platform-specific)
- Create DataExporter for JSON/CSV export functionality
- Add export_to_json() for JSON format output
- Add export_to_csv() for CSV format output
- Auto-generate timestamped filenames
- Create exports directory automatically
- Integrate temperature monitor into SystemMonitor
- Add temperature display to stats output
