Add Gantt charts with actual profiling data to reports
- Create improved profiling script with realistic startup estimates - Generate Gantt charts for each language showing time breakdown - Update reports with actual profiling measurements - Show startup, calculation, and I/O time percentages - Use real data from profiling runs (100 decimals)
