feat: Allow rust files to be used linkedProjects

With this, script files become more usable as the user can at least add them manually to the linked projects, allowing them to be used "on the (manual) fly" without having to open a separate vscode window that only has files open and no folder.

Also makes build scripts work for them (though no proc-macros, for some reason the dylib field is not populated in the output)
