cursor dev here. reasonable assumptions, but not quite the case. the snyk packages are just the names of our bundled extensions, which we never package nor upload to any registry. (we do it just like how VS Code does it: https://github.com/microsoft/vscode/tree/main/extensions)
we did not hire snyk, but we reached out to them after seeing this and they apologized. we did not get any confirmation of what exactly they were trying to do here (but i think your explanation that someone there suspected a dependency confusion vulnerability is plausible. though it's pretty irresponsible imo to do that on public npm and actually sending up the env variables)
