the Go 1.23 behavior.

### Go 1.23

Go 1.23 changed the channels created by package time to be unbuffered
(synchronous), which makes correct use of the [`Timer.Stop`](/pkg/time/#Timer.Stop)
and [`Timer.Reset`](/pkg/time/#Timer.Reset) method results much easier.
The [`asynctimerchan` setting](/pkg/time/#NewTimer) disables this change.
There are no runtime metrics for this change,
This setting will be removed in Go 1.27.

### `UploadFile` { #uploadfile }

`UploadFile` has the following attributes:

* `filename`: A `str` with the original file name that was uploaded (e.g. `myimage.jpg`).
* `content_type`: A `str` with the content type (MIME type / media type) (e.g. `image/jpeg`).

        this.commandDestroyTimeout = commandDestroyTimeout;
    }

    /**
     * Gets file extension from MIME type for creating temp files with proper extensions.
     * This helps ImageMagick correctly identify file formats.
     * @param mimeType The MIME type of the content.
     * @return The file extension including the dot (e.g., ".gif"), or empty string if unknown.
