Release LibreSpeed 6.2.1 · librespeed/speedtest

Highlights

Fixed upload-speed results being inflated when an upload request receives an HTTP error response. The client now only starts a replacement upload after the completed request returns a successful status. #820
Made the modern frontend work when the repository is served without rearranging its files. Docker now preserves the frontend/ asset directory, while settings.json and server-list.json are served from the web root. #834

Documented the request-body-size configuration required by IIS deployments.
Updated Docker, installation, and design-switch documentation to use the same layout as a non-Docker deployment.
Added end-to-end coverage for all runtime modes, Alpine standalone deployments, and the static modern-frontend asset layout.
