Single file report with history

### Describe the Bug

Hello,

We upgraded to the latest version of Allure and tried to enable the new single file report feature.

Unfortunately, while the report works fine, it doesn't generate the "history" directory. As a result, it's not possible to accumulate results from previous runs while using single file reports, unless we also generate a multi file one to get the history directory.

Did we miss something here? Is it possible to get history in single file reports?

### Steps to Reproduce

1. Collect some test data
2. Generate single file report
3. Collect more test data
4. Generate new version of single file report
5. History from the previous report is not included

### Expected Behaviour

Single file reports should still generate the history data (optionally) so that it's possible to generate single file reports with history.

### Code of Conduct

- [X] I agree to follow this project's Code of Conduct

Start by reproducing the reported sequence with Allure Report 2.30.0: generate two single-file reports from successive test-data collections and inspect whether history is preserved. Trace the single-file report generation entry point and compare it with multi-file generation, then verify that the second single-file report includes prior history without requiring a separate multi-file report.
