Get output file name of the script from another script

[KivApple]

I have two scripts generated by Rsbuild: main page script and web worker script.
In order to launch web worker from the main page script, I have to know it's file name, but output file name includes content hash (and I don't want to disable it, because it would lead to caching problems), so I cannot just hardcode it.
I need somehow obtain generated file name of web worker script from another script built by Rsbuild.
