fix: emit tool.started immediately on function_call and add duration to tool.completed (#647)

- Emit tool.started on response.output_item.added instead of .done
- Track startedAt timestamp for each tool call to calculate duration
- Include duration (2 decimal places) and error status in tool.completed
- Fix response.completed fallback to emit tool.started before tool.completed
- Update website license from MIT to BSL-1.1
